This document detailed the various initiatives implemented by Suncor Energy Inc. in light of Climate Change Voluntary Challenge and Registry (VCR) Program. Project Millennium, which represents a 3.25 billion dollar expansion expected to lead to an increase production capacity for Oil Sands operations, was consolidated during 2000, along with the completion of restructuring, which led to the divestiture of conventional oil properties and the joint venture interest held by Suncor in the Stuart Oil Shale Project. In addition, there were some improvements made to the greenhouse gas management and reporting systems. Suncor is expected to invest funding in the order of 100 million dollars for the period 2000-2005 in the field of alternative and renewable energy. The reductions in greenhouse gas emissions achieved for the year 2000 were 404,000 tonnes carbon dioxide equivalent. Each of these major endeavours was discussed in the document. tabs.

that discretionary judgement takes place and will impact on the screening decision. This article examines the results of discretion involved in screening of climate change plans (CCPs) in a Danish context. These years voluntary CCPs are developed as a response to the global and local emergence of both mitigation...... and adap- tation, and the voluntary commitment by the local authorities is an indication of an emerging norm of climate change as an important issue. This article takes its point of departure in the observation that SEA is not undertaken for these voluntary CCPs. The critical analysis of this phenomenon...... rests upon a docu- mentary study of Danish CCPs, interviews with a lawyer and ministerial key person and informal discussions between researchers, practitioners and lawyers on whether climate change plans are covered by SEA legislation and underlying reasons for the present practice. Based on a critical...

Cerebrovascular oxygenation changes during respiratory challenges have clinically important implications for brain function, including cerebral autoregulation and the rate of brain metabolism. SWI is sensitive to venous oxygenation level by exploitation of the magnetic susceptibility of deoxygenated blood. We assessed cerebral venous blood oxygenation changes during simple voluntary breath-holding (apnea) and hyperventilation by use of SWI at 3T. We performed SWI scans (3T; acquisition time of 1 minute, 28 seconds; centered on the anterior commissure and the posterior commissure) on 10 healthy male volunteers during baseline breathing as well as during simple voluntary hyperventilation and apnea challenges. The hyperventilation and apnea tasks were separated by a 5-minute resting period. SWI venograms were generated, and the signal changes on SWI before and after the respiratory stress tasks were compared by means of a paired Student t test. Changes in venous vasculature visibility caused by the respiratory challenges were directly visualized on the SWI venograms. The venogram segmentation results showed that voluntary apnea decreased the mean venous blood voxel number by 1.6% (P hyperventilation increased the mean venous blood voxel number by 2.7% (P < .0001). These results can be explained by blood CO2 changes secondary to the respiratory challenges, which can alter cerebrovascular tone and cerebral blood flow and ultimately affect venous oxygen levels. These results highlight the sensitivity of SWI to simple and noninvasive respiratory challenges and its potential utility in assessing cerebral hemodynamics and vasomotor responses. © 2014 by American Journal of Neuroradiology.

Kashmir valley is a major saffron (Crocus sativus Kashmirianus) growing area of the world, second only to Iran in terms of production. In Kashmir, saffron is grown on uplands (termed in the local language as “Karewas”), which are lacustrine deposits located at an altitude of 1585 to 1677 m above mean sea level (amsl), under temperate climatic conditions. Kashmir, despite being one of the oldest historical saffron-producing areas faces a rapid decline of saffron industry. Among many other factors responsible for decline of saffron industry the preponderance of erratic rainfalls and drought-like situation have become major challenges imposed by climate change. Saffron has a limited coverage area as it is grown as a ‘niche crop’ and is a recognized “geographical indication,” growing under a narrow microclimatic condition. As such it has become a victim of climate change effects, which has the potential of jeopardizing the livelihood of thousands of farmers and traders associated with it. The paper discusses the potential and actual impact of climate change process on saffron cultivation in Kashmir; and the biotechnological measures to address these issues. PMID:25072266
In 1989 the Scottish Health Education Group and the Scottish Association for Counselling compiled a directory of counselling services in Scotland. When asked if they offered counselling, the great majority of voluntary sector organisations in the welfare field said that they did, and they were therefore included in the directory, generating over 500 entries in total, including, among others, all the Citizens Advice Bureaux in Scotland. In 2001, I was involved in the implementat...
Full Text Available Adolescence is associated with high impulsivity and risk taking, making adolescent individuals more inclined to use drugs. Early drug use is correlated to increased risk for substance use disorders later in life but the neurobiological basis is unclear. The brain undergoes extensive development during adolescence and disturbances at this time are hypothesized to contribute to increased vulnerability. The transition from controlled to compulsive drug use and addiction involve long-lasting changes in neural networks including a shift from the nucleus accumbens, mediating acute reinforcing effects, to recruitment of the dorsal striatum and habit formation. This study aimed to test the hypothesis of increased dopamine release after a pharmacological challenge in adolescent rats. Potassium-evoked dopamine release and uptake was investigated using chronoamperometric dopamine recordings in combination with a challenge by amphetamine in early and late adolescent rats and in adult rats. In addition, the consequences of voluntary alcohol intake during adolescence on these effects were investigated. The data show a gradual increase of evoked dopamine release with age, supporting previous studies suggesting that the pool of releasable dopamine increases with age. In contrast, a gradual decrease in evoked release with age was seen in response to amphetamine, supporting a proportionally larger storage pool of dopamine in younger animals. Dopamine measures after voluntary alcohol intake resulted in lower release amplitudes in response to potassium-chloride, indicating that alcohol affects the releasable pool of dopamine and this may have implications for vulnerability to addiction and other psychiatric diagnoses involving dopamine in the dorsal striatum.

A number of studies have shown that stress and an activated hypothalamic-pituitary-adrenal (HPA) axis are associated with increased voluntary alcohol drinking. Recently, associations have been found between activated HPA and hypothalamic-pituitary-gonadal (HPG) axes in alcohol-preferring AA and non-preferring ANA, F2 (crossbred second generation from original AA and ANA), and Wistar rats. The aim of the present study has been to determine the role of corticosterone and alcohol-related testosterone-effects in subsequent alcohol drinking in AA, ANA, F2 and Wistar rats. The present study comprises of four substudies presenting new analyses of existing data, by which correlations between basal corticosterone levels, changes in testosterone levels during alcohol intoxications and subsequent voluntary alcohol consumption are investigated. The results displayed positive correlations between basal corticosterone levels and subsequent alcohol-mediated testosterone elevations, which was positively associated with voluntary alcohol consumption. The results also showed a negative correlation between basal corticosterone levels and alcohol-mediated testosterone decreases, which was negatively associated with alcohol consumption. In conclusion, the present study displays novel results, according to which the HPA axis, one hand, relates to testosterone elevation (potentially causing and/or strengthening reinforcement) during alcohol intoxication, which in turn may relate to higher voluntary alcohol consumption (AA rats). Vice versa, the HPA axis may also relate to alcohol-mediated testosterone decrease (causing testosterone reduction and disinforcement) and low-alcohol drinking (ANA, F2 and Wistar rats). In addition, the present results showed that alcohol-mediated testosterone changes may also, independently of the HPA axis, correlate with voluntary alcohol drinking, which indicate the impact of genetic factors. Thus, the role of the HPA-axis may be more related to situational

Full Text Available This paper aims to study the factors that influence the decision of voluntary change of the audit firm. In Brazil there is a requirement of compulsory replacement (audit rotation for at least every 5 years and at intervals of 3 years for their rehiring. However, during the period of adoption of international accounting standards, the brazilian securities regulator – CVM, has suspended the requirement, what turns the period of 2010 to 2014 interesting to this research. Previous studies relate the auditor's change decision with auditor characteristics and their relationship with the client; firm characteristics and changes in the top management; and corporate governance mechanisms. This paper aims to investigate if these and other variables explain its phenomenon in the brazilian market, characterized by the concentration of control and low protection of minority investor. The results suggest that a modified audit report, the company’s growth and being listed in Novo Mercado or Nível 2, segments of more demanding requirements of coroporate governance of BM&FBovespa, increase the likelihood of replacement of auditors; while hiring non-audit services reduces the probability of voluntary change.

Full Text Available The repetitive discharges required to produce a sustained muscle contraction results in activity-dependent hyperpolarization of the motor axons and a reduction in the force-generating capacity of the muscle. We investigated the relationship between these changes in the adductor pollicis muscle and the motor axons of its ulnar nerve supply, and the reproducibility of these changes. Ten subjects performed a 1-min maximal voluntary contraction. Activity-dependent changes in axonal excitability were measured using threshold tracking with electrical stimulation at the wrist; changes in the muscle were assessed as evoked and voluntary electromyography (EMG and isometric force. Separate components of axonal excitability and muscle properties were tested at 5 min intervals after the sustained contraction in 5 separate sessions. The current threshold required to produce the target muscle action potential increased immediately after the contraction by 14.8% (p<0.05, reflecting decreased axonal excitability secondary to hyperpolarization. This was not correlated with the decline in amplitude of muscle force or evoked EMG. A late reversal in threshold current after the initial recovery from hyperpolarization peaked at -5.9% at ∼35 min (p<0.05. This pattern was mirrored by other indices of axonal excitability revealing a previously unreported depolarization of motor axons in the late recovery period. Measures of axonal excitability were relatively stable at rest but less so after sustained activity. The coefficient of variation (CoV for threshold current increase was higher after activity (CoV 0.54, p<0.05 whereas changes in voluntary (CoV 0.12 and evoked twitch (CoV 0.15 force were relatively stable. These results demonstrate that activity-dependent changes in motor axon excitability are unlikely to contribute to concomitant changes in the muscle after sustained activity in healthy people. The variability in axonal excitability after sustained activity
Full Text Available Scaling up voluntary medical male circumcision (VMMC for HIV prevention is cost saving and creates fiscal space in the future that otherwise would have been encumbered by antiretroviral treatment costs. An investment of US$1,500,000,000 between 2011 and 2015 to achieve 80% coverage in 13 priority countries in southern and eastern Africa will result in net savings of US$16,500,000,000. Strong political leadership, country ownership, and stakeholder engagement, along with effective demand creation, community mobilisation, and human resource deployment, are essential. This collection of articles on determining the cost and impact of VMMC for HIV prevention signposts the way forward to scaling up VMMC service delivery safely and efficiently to reap individual- and population-level benefits.

Full Text Available Voluntary medical male circumcision (VMMC is capable of reducing the risk of sexual transmission of HIV from females to males by approximately 60%. In 2007, the WHO and the Joint United Nations Programme on HIV/AIDS (UNAIDS recommended making VMMC part of a comprehensive HIV prevention package in countries with a generalized HIV epidemic and low rates of male circumcision. Modeling studies undertaken in 2009-2011 estimated that circumcising 80% of adult males in 14 priority countries in Eastern and Southern Africa within five years, and sustaining coverage levels thereafter, could avert 3.4 million HIV infections within 15 years and save US$16.5 billion in treatment costs. In response, WHO/UNAIDS launched the Joint Strategic Action Framework for accelerating the scale-up of VMMC for HIV prevention in Southern and Eastern Africa, calling for 80% coverage of adult male circumcision by 2016. While VMMC programs have grown dramatically since inception, they appear unlikely to reach this goal. This review provides an overview of findings from the PLOS Collection "Voluntary Medical Male Circumcision for HIV Prevention: Improving Quality, Efficiency, Cost Effectiveness, and Demand for Services during an Accelerated Scale-up." The use of devices for VMMC is also explored. We propose emphasizing management solutions to help VMMC programs in the priority countries achieve the desired impact of averting the greatest possible number of HIV infections. Our recommendations include advocating for prioritization and funding of VMMC, increasing strategic targeting to achieve the goal of reducing HIV incidence, focusing on programmatic efficiency, exploring the role of new technologies, rethinking demand creation, strengthening data use for decision-making, improving governments' program management capacity, strategizing for sustainability, and maintaining a flexible scale-up strategy informed by a strong monitoring, learning, and evaluation platform.

Given the onset of alcohol use, neurological sensitivity, and enhanced panic-relevant vulnerability, adolescence is a key period in which to study the documented linkage between alcohol and panic-related problems. The current study was designed to build upon and uniquely extend extant work via (a) utilization of well-established experimental psychopathology techniques and (b) evaluation of unique associations between alcohol use and panic symptoms after controlling for theoretically relevant behavioral, environmental, and individual difference variables (i.e., age, gender, negative affectivity, anxiety sensitivity, child and parent tobacco use, and parental panic disorder). Participants were 111 community-recruited adolescents ages 12-17 years (M = 15.76 years; n = 50 girls). Youth completed a battery of well-established questionnaires and a voluntary hyperventilation challenge, and parents present at the laboratory completed a structured clinical interview. Adolescent alcohol use was categorized as Non-Users, Experimenters, or Users. Panic symptoms were indexed via retrospective self-report and adolescents' response to a biological challenge procedure (i.e., voluntary hyperventilation). After controlling for theoretically relevant covariates, Users evidenced elevated panic-relevant symptoms and responding compared with Non-Users; Experimenters did not differ from Non-Users. Findings suggest alcohol use history is uniquely associated with panic symptomatology among youth, including "real-time" reactivity elicited by a laboratory challenge. Although there is significant work yet to be done, these data advance extant work and lay the groundwork for the types of sophisticated designs that will be needed to answer the most pressing and complex questions regarding the link between alcohol use and panic symptoms among adolescents. 2013 APA, all rights reserved

Linear growth curve modeling was used to compare rates of change in functional status between three groups of older adults: Individuals holding voluntary lay leadership positions in a church, regular church attenders who were not leaders, and those not regularly attending church. Functional status was tracked longitudinally over a 4-year period in a national sample of 1,152 Black and White older adults whose religious backgrounds were either Christian or unaffiliated. Leaders had significantly slower trajectories of increase in both the number of physical impairments and the severity of those impairments. Although regular church attenders who were not leaders had lower mean levels of impairment on both measures, compared with those not regularly attending church, the two groups of non-leaders did not differ from one another in their rates of impairment increase. Leadership roles may contribute to longer maintenance of physical ability in late life, and opportunities for voluntary leadership may help account for some of the health benefits of religious participation.

Full Text Available Objective: The aim of this study was comparing the ground reaction forces, center of pressure and body center of mass changes in voluntary, semi-voluntary and involuntary gait termination in healthy young men. Methods: In this study, 12 young men performed termination of gait in three different patterns. The variable of peak antero-posterior and vertical forces in two directions at both limbs, the time to reach peak and average forces in every limb in both directions, the center of pressure displacement of medio-lateral and antero-posterior direction for each limb and the net center of pressure and the displacement of the center of mass motion in all three motion plates were recorded using motion analysis system and force plate.The repeated measurements test was used to compare three patterns of gait termination at significance level of p&le0.5. Results: The results showed a significant difference in variables of peak antero-posterior force, the time to reach peak antero-posterior force and mean antero-posterior forces of the leading limb, the peak antero-posterior force of the trialing limbs, the depth force of leading limbs, medio-lateral cop of leading limbs displacement and vertical displacement of the center of mass, among different patterns of gait termination. Conclusion: While walking, the probability of a fall or collision damage, when a sudden or unexpected stop is required, increases. Therefore, more coordination between neuromuscular systems is required.

For food manufacturers, the label on a food package is a tool meant to alert consumers to the presence of specific allergens, allowing consumers to make informed decisions and not unnecessarily limit their food choices. Mandatory allergen labeling is used when the allergen is an intentionally added ingredient, whereas voluntary allergen labeling is used when the presence of the allergen is unintentional and may be in the finished product as a result of cross-contact. In a globalized economy, ensuring food safety is a growing challenge for manufacturers. When ingredients and technologies are sourced worldwide from multiple business partners, complexity rises, which can increase the chance for errors, leading to potential harm. Threshold science, Voluntary Incidental Trace Allergen Labelling (VITAL) reference doses, fit-for-purpose analytical technology, and common sense enable us to optimize allergen management for the benefit of allergic consumers. This is a good strategy because all stakeholders share the common goal of making foods safe and wholesome for all. Herein, we recommend that (1) senior management make science-based thresholds a priority for both regulatory authorities and the food industry; (2) VITAL 2.0 be adopted as a risk assessment and risk management tool for precautionary allergen labeling (PAL); (3) a standardized message for PAL, i.e., "may contain x," be used to make it easily understandable to allergic consumers so they can make informed food choices; and (4) validated fit-for-purpose allergen methods be used to meet analytical needs. This is an opportunity for us to speak with one voice and demonstrate that food safety is not a competitive issue, but a shared responsibility. This approach could significantly improve allergic consumers' lives.

Physical exercise, besides improving cognitive and mental health, is known to cause structural changes in the brain. Understanding the structural changes that occur with exercise as well as the neuroanatomical correlates of a predisposition for exercise is important for understanding human health. This study used high-resolution 3D MR imaging, in combination with deformation-based morphometry, to investigate the macroscopic changes in brain structure that occur in healthy adult mice following four weeks of voluntary exercise. We found that exercise induced changes in multiple brain structures that are involved in motor function and learning and memory including the hippocampus, dentate gyrus, stratum granulosum of the dentate gyrus, cingulate cortex, olivary complex, inferior cerebellar peduncle and regions of the cerebellum. In addition, a number of brain structures, including the hippocampus, striatum and pons, when measured on MRI prior to the start of exercise were highly predictive of subsequent exercise activity. Exercise tended to normalize these pre-existing differences between mice. Copyright © 2015 Elsevier Inc. All rights reserved.

Programs that recognize restaurants for offering healthful options have emerged as a popular strategy to address the obesity epidemic; however, program fidelity and business responses to such programs are rarely assessed. This study sought to examine how retail restaurants in Los Angeles County chose to comply with participation criteria required by the Choose Health LA Restaurants initiative in the region; the program recognizes restaurants for offering reduced-size portions and healthy children's meals. Menus of all restaurants that joined within 1 year of program launch (n = 17 restaurant brands) were assessed for changes. Nine of the 17 brands made changes to their menus to meet participation criteria for reduced-size portions while 8 of the 10 restaurant brands that offered children's menus made changes to improve the healthfulness of children's meals. Results of this comparative assessment lend support to restaurant compliance with program criteria and menu improvements, even though they are voluntary, representing an important step toward implementing this strategy in the retail environment.

Full Text Available As an HIV prevention strategy, the scale-up of voluntary medical male circumcision (VMMC is underway in 14 countries in Africa. For prevention impact, these countries must perform millions of circumcisions in adolescent and adult men before 2015. Although acceptability of VMMC in the region is well documented and service delivery efforts have proven successful, countries remain behind in meeting circumcision targets. A better understanding of men's VMMC-seeking behaviors and experiences is needed to improve communication and interventions to accelerate uptake. To this end, we conducted semi-structured interviews with 40 clients waiting for surgical circumcision at clinics in Zambia. Based on Stages of Change behavioral theory, men were asked to recount how they learned about adult circumcision, why they decided it was right for them, what they feared most, how they overcame their fears, and the steps they took to make it to the clinic that day. Thematic analysis across all cases allowed us to identify key behavior change triggers while within-case analysis elucidated variants of one predominant behavior change pattern. Major stages included: awareness and critical belief adjustment, norming pressures and personalization of advantages, a period of fear management and finally VMMC-seeking. Qualitative comparative analysis of ever-married and never-married men revealed important similarities and differences between the two groups. Unprompted, 17 of the men described one to four failed prior attempts to become circumcised. Experienced more frequently by older men, failed VMMC attempts were often due to service-side barriers. Findings highlight intervention opportunities to increase VMMC uptake. Reaching uncircumcised men via close male friends and female sex partners and tailoring messages to stage-specific concerns and needs would help accelerate men's movement through the behavior change process. Expanding service access is also needed to meet

Full Text Available BACKGROUND: This paper proposes an approach to estimating the costs of demand creation for voluntary medical male circumcision (VMMC scale-up in 13 countries of eastern and southern Africa. It addresses two key questions: (1 what are the elements of a standardized package for demand creation? And (2 what challenges exist and must be taken into account in estimating the costs of demand creation? METHODS AND FINDINGS: We conducted a key informant study on VMMC demand creation using purposive sampling to recruit seven people who provide technical assistance to government programs and manage budgets for VMMC demand creation. Key informants provided their views on the important elements of VMMC demand creation and the most effective funding allocations across different types of communication approaches (e.g., mass media, small media, outreach/mobilization. The key finding was the wide range of views, suggesting that a standard package of core demand creation elements would not be universally applicable. This underscored the importance of tailoring demand creation strategies and estimates to specific country contexts before estimating costs. The key informant interviews, supplemented by the researchers' field experience, identified these issues to be addressed in future costing exercises: variations in the cost of VMMC demand creation activities by country and program, decisions about the quality and comprehensiveness of programming, and lack of data on critical elements needed to "trigger the decision" among eligible men. CONCLUSIONS: Based on this study's findings, we propose a seven-step methodological approach to estimate the cost of VMMC scale-up in a priority country, based on our key assumptions. However, further work is needed to better understand core components of a demand creation package and how to cost them. Notwithstanding the methodological challenges, estimating the cost of demand creation remains an essential element in deriving
Prepared for the future? Evaluating the costs and benefits of voluntary work for natural disaster management under a changing climate - data on recent flood events, stakeholder needs and policy applications

Voluntary emergency and relief services, such as fire brigades or rescue organisations, form the backbone of disaster management in most of European countries. In Austria, disaster management relies on the cooperation between governmental and non-governmental institutions: When a disaster occurs, the volunteer organizations act as auxiliaries to the responsible disaster management authority. The assessment of costs and benefits of these emergency services is a crucial component of risk and disaster management strategies, since public means are getting scarcer and these costs can reach critical levels for low-income municipalities. As extreme events and emergency operations are likely to increase due to climate change, the efficient allocation of public budgets for risk and disaster management becomes more important. Hence, both, the costs and the benefits must be known, but voluntary and professional work is hardly documented and assessed comprehensively. Whereas the costs of emergency services can be calculated using market values and an analysis of public and institutional budgets, the benefits of voluntary efforts cannot be assessed easily. We present empirical data on costs of voluntary and professional emergency services during the floods of 2002, 2005 and 2013 in Austria and Germany on different scales, obtained from public authorities, fire brigades and by means of public surveys. From these results, we derive a calculation framework and data requirements for assessing costs of emergency services. To consider the different stakeholders needs of administration, emergency institutions and voluntary members, we carried out workshops, first to identify future challenges in voluntary work for disaster management instigated by climate change and second, to develop approaches how the voluntary system can be uphold when facing increasing adverse impacts of natural hazards. The empirical results as well as the workshop outcome shall be translated into policy
The latest scientific knowledge on climate change indicates that higher greenhouse gas concentrations in the atmosphere through unchecked emissions will provoke severe climate change and ocean acidification threatening environmental structures on which humanity relies. Climate change therefore poses major socio-economic, technical and environmental challenges which will have serious impacts on countries’ pathways towards sustainable development. As a result, climate change and sustainable development have increasingly become interlinked. A changing climate makes achieving Millennium Development Goals more difficult and expensive, so there is every reason to achieve development goals with low greenhouse gas emissions. This leads to the following five challenges discussed by Challenges and Solutions for Climate Change: To place climate negotiations in the wider context of sustainability, equity and social change so that development benefits can be maximised at the same time as decreasing greenhouse gas emissi...

Previous studies have shown that visual images can produce rapid changes in testosterone concentrations. We explored the acute effects of video clips on salivary testosterone and cortisol concentrations and subsequent voluntary squat performance in highly trained male athletes (n=12). Saliva samples were collected on 6 occasions immediately before and 15 min after watching a brief video clip (approximately 4 min in duration) on a computer screen. The watching of a sad, erotic, aggressive, training motivational, humorous or a neutral control clip was randomised. Subjects then performed a squat workout aimed at producing a 3 repetition maximum (3RM) lift. Significant (Ppre-workout environment offers an opportunity for understanding the outcomes of hormonal change, athlete behaviour and subsequent voluntary performance. Copyright © 2011 Elsevier Inc.

Full Text Available The aim of this paper is to uncover emerging challenges of peacekeeping operations, determine the changes in command actions and its effects on the professional preparation of commanders by analyzing experiences of military officers. To that end the research data were collected by means of structured face-to- face interviews with voluntary participation of fourteen officers, who took charge in various peacekeeping operations. The collected data were analyzed based on the content analysis method. Findings indicate that peacekeeping operations pose specific challenges for peacekeepers, necessitate changes in command action in terms of flexibility and new precautions in terms of preparation of commanders.

Full Text Available The climate change issue has become increasingly present in our society in the last decade and central also to communication studies. In the e-book “Communicating Climate Change: Discourses, Mediations and Perceptions”, edited by Anabela Carvalho, various scholars investigate how climate change challenges communication by looking at three main aspects: the discourses of a variety of social actors on climate change; the reconstruction of those discourses in the media; the citizens’ perceptions, understandings and attitudes in relation to climate change.

Full Text Available The purpose of this study was to determine how voluntary drinking is affected by the simultaneous presence of two different beverages (plain water and a sports drink compared to the availability of just one beverage at a time. Methods: Twenty recreational cyclists and triathletes (22.8 ± 6.9 years old were recruited. Subjects completed three laboratory sessions each (DB=23°C, RH=70% in randomly assigned order, with at least one week between sessions: one session, only water available (WAonly; another session, only sports drink (SDonly; and another session, both beverages (BOTH. Drinking was ad libitum. Each exercise session lasted 100 min.: a 20 min. warm-up, followed by eight 5-min. high-intensity intervals (85-95% HRmax alternating with 2.5 min. recovery time (60-70% HRmax and a final 20 min. recovery (60-70% HRmax. Fluid ingestion was measured each 20 min. Taste scores for both fluids (W and SD and body weight were also measured before and after each exercise session. Results: No significant differences were found for total fluid ingestion when comparing BOTH and SDonly (846.1 ñ 382.7 vs. 827.9 ñ 365.6 mL, respectively, p > 0.05.

This paper discusses emerging demographic patterns and its opportunities and challenges for India. It investigates the specificities in the demographic transition in terms of various demographic parameters and the lack of homogeneity in the transition across states in the country. It presents some opportunities that can arise from having demographic changes, particularly the demographic dividend and interstate migration to overcome labor shortage in some parts. At the same time, there are serious challenges in the form of enhancing human capital development, addressing the issue of skewed sex ratio, and the possible rise in social and political unrest and conflict.

Lakes comprise a tiny fraction of Earth's surface, but contribute significantly to human life and wellbeing. Many lakes are disappearing due to climate change and water diversions, and there are widespread disruptions to ecosystem processes due to human influences. For example, pollution by nutrients and toxic chemicals causes toxicity to humans, livestock, fish, and wildlife. Lake desiccation reduces economic opportunity and food security, displacing entire communities. Understanding these changes at the global scale, and their implications for human societies, are a key challenges for aquatic scientists. In this talk, I will use results from my research to highlight some of the key uncertainties related to global change and lakes, as well as recent developments by aquatic scientists aimed at predicting, mitigating, and coping with these changes.

Transcranial magnetic stimulation (TMS) gives rise to muscle responses, known as motor evoked potentials (MEP), through activation of the motor pathways. Voluntary contraction causes facilitation of MEPs, which consists of shortening MEP latency, increasing MEP amplitude and widening MEP duration. While an increase in excitability of alpha motorneurons and the corticospinal tract can easily explain latency shortening and amplitude increase, other mechanisms have to be accounted for to explain the increase in duration. We measured the increase in duration of the MEP during contraction with respect to rest in a group of healthy volunteers and retrospectively assessed this parameter in patients who were examined in a standardized fashion during the past 5 years. We included 25 healthy subjects, 21 patients with multiple sclerosis, 33 patients with acute stroke, 5 patients with hereditary spastic paraparesis, and 5 patients with signs suggesting psychogenic paresis. We found already significant differences among groups in the MEP duration at rest, patients with MS had a significantly longer duration, and patients with stroke had significantly shorter duration, than the other two groups. The increase in MEP duration during voluntary contraction was different in patients and in healthy subjects. It was significantly shorter in MS and significantly longer in stroke patients. It was absent in the five patients with suspected psychogenic weakness. In patients with HSP, an abnormally increase in duration occurred only in leg muscles. Our results suggest that the increase in duration of the MEP during contraction may reveal the contribution of propriospinal interneurons to the activation of alpha motorneurons. This mechanism may be altered in some diseases and, therefore, the assessment proposed in this work may have clinical applicability for the differential diagnosis of weakness. PMID:26793051

Population growth and the pressures spawned by increasing demands for energy and resource-intensive goods, foods, and services are driving unsustainable growth in greenhouse gas (GHG) emissions. Recent GHG emission trends are consistent with worst-case scenarios of the previous decade. Dramatic and near-term emission reductions likely will be needed to ameliorate the potential deleterious impacts of climate change. To achieve such reductions, fundamental changes are required in the way that energy is generated and used. New technologies must be developed and deployed at a rapid rate. Advances in carbon capture and storage, renewable, nuclear and transportation technologies are particularly important; however, global research and development efforts related to these technologies currently appear to fall short relative to needs. Even with a proactive and international mitigation effort, humanity will need to adapt to climate change, but the adaptation needs and damages will be far greater if mitigation activities are not pursued in earnest. In this review, research is highlighted that indicates increasing global and regional temperatures and ties climate changes to increasing GHG emissions. GHG mitigation targets necessary for limiting future global temperature increases are discussed, including how factors such as population growth and the growing energy intensity of the developing world will make these reduction targets more challenging. Potential technological pathways for meeting emission reduction targets are examined, barriers are discussed, and global and US. modeling results are presented that suggest that the necessary pathways will require radically transformed electric and mobile sectors. While geoengineering options have been proposed to allow more time for serious emission reductions, these measures are at the conceptual stage with many unanswered cost, environmental, and political issues. Implications: This paper lays out the case that mitigating the
N/NIH rats (N = 10) were implanted with venous catheters to permit stressless chronic, repeated blood withdrawal. Following surgical recovery, the rats were restrained to a lab counter top for 30 min after injection with saline or low dose (0.5 g/kg) ethanol. Blood was repeatedly withdrawn to determine AUC production of NE and E to assess the effect that low dose ethanol has on stress responsiveness. Between saline injection restraint and ethanol injection restraint conditions no differences in NE or E AUC were apparent. A 2- bottle preference test for ethanol was then performed over 21 days. Multiple regression analyses of NE saline restraint and ethanol restraint could predict ethanol consumption to the p = .02 level with R/sup 2/ = .681. Multiple regressions of E saline restraint and E ethanol restraint could predict ethanol consumption to the p = .01 level with R/sup 2/ = .746. These data suggest that ethanol induced increases in plasma NE and E during stress can predict later voluntary ethanol consumption between the ranges of .13 and 1.05 g ethanol/kg/day. This data seems to be more in line with an arousal or withdrawal relationship between ethanol consumption and stress than by a simple tension reduction formulation based on plasma NE or E.

Our goal in this article is to explicate the way, and the extent to which, euthanasia can be voluntary from both the perspective of the patient and the perspective of the health care providers involved in the patient's care. More significantly, we aim to challenge the way in which those engaged in ongoing philosophical debates regarding the morality of euthanasia draw distinctions between voluntary, involuntary, and nonvoluntary euthanasia on the grounds that drawing the distinctions in the traditional manner (1) fails to reflect what is important from the patient's perspective and (2) fails to reflect the significance of health care providers' interests, including their autonomy and integrity.

Trouble in polar paradise (Science, 08/30/02), significant changes in the Arctic environment are scientifically documented (R.E. Moritz et al. ibid.). More trouble, lots more, "abrupt climate change," (R. B. Alley, et al. Science 03/28/03). R. Corell, Arctic Climate Impact Assessment team (ACIA), "If you want to see what will happen in the rest of the world 25 years from now just look what's happening in the Arctic," (Arctic Council meeting, Iceland, 08/03). What to do? Make abrupt Arctic climate change a grand challenge for the IPY-4 and beyond! Scientifically:Describe the "state" of the Arctic climate system as succinctly as possible and accept it as the point of departure.Develop a hypothesis and criteria what constitutes "abrupt climate change," in the Arctic that can be tested with observations. Observations: Bring to bear existing observations and coordinate new investments in observations through an IPY-4 scientific management committee. Make the new Barrow, Alaska, Global Climate Change Research Facility a major U.S. contribution and focal point for the IPY-4 in the U.S Arctic. Arctic populations, Native peoples: The people of the North are living already, daily, with wrenching change, encroaching on their habitats and cultures. For them "the earth is faster now," (I. Krupnik and D. Jolly, ARCUS, 2002). From a political, economic, social and entirely realistic perspective, an Arctic grand challenge without the total integration of the Native peoples in this effort cannot succeed. Therefore: Communications must be established, and the respective Native entities must be approached with the determination to create well founded, well functioning, enduring partnerships. In the U.S. Arctic, Barrow with its long history of involvement and active support of science and with the new global climate change research facility should be the focal point of choice Private industry: Resource extraction in the Arctic followed by oil and gas consumption, return the combustion

On 10 April last, the Dutch Senat accepted a new bill concerning voluntary active euthanasia and physician assisted suicide. This bill legally embodies a ground for exemption from punishment for physicians who conducted voluntary active euthanasia or physician assisted suicide and who complied with certain requirements. Hence, the old policy of tolerance has been transformed into a legal system of acceptance of certain forms of voluntary active euthanasia and physician assisted suicide. This contribution describes these legal changes as the final stage of a process of integration of voluntary active euthanasia and physician assisted suicide in Dutch society. In this way, it endeavours to contribute to a constructive debate.

Glucose, the predominant energy substrate of the central and peripheral nervous system, is delivered to neurons via a family of facilitative glucose transporters (GLUT). The majority of glucose is transported to the brain via glucose transporter 1 (GLUT1) located on epithelial cells of capillaries and on the astrocytes that wrap around them. Changes in neuronal activity are linked to increases in glucose demand and local cerebral glucose utilization. Current research has indicated a corresponding change in GLUT1 expression in response to increased metabolic demand in operant tasks. The purpose of this study was to examine, in the mouse brain, the effects of neuronal activation induced by voluntary running on the plastic expression of vascular GLUT1 and neuronal plasticity as measured by the microtubule protein beta-tubulin III (Tuj). The results showed that access to a running wheel for 48h induced plastic changes in the expression of GLUT1, Tuj and GLUT1-associated estimate of astrocyte vascular endfeet in motor regions. The results tend to support the plastic association between mechanisms of energy supply and plastic reorganization of neurons following a new training experience. Copyright © 2012 Elsevier B.V.

Incomplete voluntary muscle activation may contribute to impaired muscle mechanical function and physical function in older adults. Exercise interventions have been shown to increase voluntary muscle activation, although the evidence is sparse for mobility-limited older adults, particularly in association with physical function. This study examined the effects of 12weeks of power training on outcomes of voluntary muscle activation and gait speed in mobility-limited older adults from the Healthy Ageing Network of Competence (HANC) study. We included 37 older men and women with a usual gait speed of power training, 2 sessions per week; age: 82.3±1.3years, 56% women) and n=21 in the control group (CG: no interventions; age: 81.6±1.1years, 67% women). Knee extensor muscle thickness (ultrasonography), strength (isokinetic dynamometry), voluntary activation (interpolated twitch technique), and gait speed (2-min maximal walking test) were assessed at baseline and post-intervention. At baseline, TG and CG were comparable for all measures. Post-intervention, significant between-group changes (TG vs. CG; pmuscle activation (+6.2%), muscle strength (+13.4Nm), and gait speed (+0.12m/s), whereas the between-group change in muscle thickness was non-significant (+0.08cm). Improvements in voluntary muscle activation were associated with improvements in gait speed in TG (r=0.67, pmuscle activation is improved in mobility-limited older adults following 12-weeks of progressive power training, and is associated with improved maximal gait speed. Incomplete voluntary muscle activation should be considered one of the key mechanisms influencing muscle mechanical function and gait speed in older adults. Copyright © 2016 Elsevier Inc.

Full Text Available There is an increasing prevalence of overweight in preadolescents that predicts physical problems over the lifespan. Physical inactivity has been implicated as an associated factor, with African American youth being at an increased risk. Based on social cognitive theory, and proposed correlates of physical activity in youth, changes over 12 weeks in measures of self-appraisal (general self, physical appearance, physical self-concept, exercise barriers self-efficacy and mood (tension, vigor, and their relations with voluntary physical activity changes, were assessed within an after-school care physical activity intervention. Participants were volunteers recruited from children already registered for a 12-week segment of YMCA after-school care. The treatment group consisted of 146 African American preadolescents with the control group comprised of 123 African American preadolescents who were scheduled to receive the program during the next sequence that it was offered. Results indicated the intervention group reported significantly more positive self-appraisals, reduced tension, and enhanced vigor. Bivariate and multiple regression analyses indicated that when each of the 4 self-appraisal and 2 mood factors were simultaneously entered into a regression equation, 36% of the variance in voluntary physical activity was explained. Findings support the treatment's association with theoretically based correlates of physical activity in the present sample, and suggest directions for physical activity interventions for youth

Full Text Available Encouraging individuals to take action is important for the overall success of climate change mitigation. Campaigns promoting climate change mitigation could address particular groups of the population on the basis of what kind of mitigation actions the group is already taking. To increase the knowledge of such groups performing similar mitigation actions we conducted a population-based cross-sectional study in Finland. The study population comprised 1623 young adults who returned a self-administered questionnaire (response rate 64%. Our aims were to identify groups of people engaged in similar climate change mitigation actions and to study the gender differences in the grouping. We also determined if socio-demographic characteristics can predict group membership. We performed latent class analysis using 14 mitigation actions as manifest variables. Three classes were identified among men: the Inactive (26%, the Semi-active (63% and the Active (11% and two classes among women: the Semi-active (72% and the Active (28%. The Active among both genders were likely to have mitigated climate change through several actions, such as recycling, using environmentally friendly products, preferring public transport, and conserving energy. The Semi-Active had most probably recycled and preferred public transport because of climate change. The Inactive, a class identified among men only, had very probably done nothing to mitigate climate change. Among males, being single or divorced predicted little involvement in climate change mitigation. Among females, those without tertiary degree and those with annual income €≥16801 were less involved in climate change mitigation. Our results illustrate to what extent young adults are engaged in climate change mitigation, which factors predict little involvement in mitigation and give insight to which segments of the public could be the audiences of targeted mitigation campaigns.

In this eighth annual report in support of the Voluntary Challenge and Registry Program, Shell Canada Ltd. has continued to improve on its overall environmental performance. The construction of the Athabasca Oil Sands Project, including the Muskeg River mine located north of Fort McMurray, Alberta, as well as and upgrader adjacent to Shell's Scotford refinery near Fort Saskatchewan, Alberta, continued in 2001. In September 2001, Shell's climate change strategy was approved. It led to the development of several management practices to provide leadership for greenhouse gas management and emission control. The target of successfully have all major facilities registered to the international environmental management system standard (ISO) 14001 was achieved. Also registered were the corporate health, safety and sustainable development (HSSD) and Resources business unit HSSD management systems. Adjustments were made to the 1990 baseline, due to the divestment of businesses in the 1990s. In 2001, the emissions of greenhouse gases were 76,000 tonnes lower than those recorded for the year 2002. The Resources business unit reduced its energy consumption by 2 per cent in 2001, as planned. Other initiatives concerning energy consumption are currently being implemented, notably at the Peace River complex and the Waterton gas complex. 6 figs.

Full Text Available Change is inevitable. Today more than ever the pace of change is accelerating. Where there is organizational change there will be resistance to this change. To deal with the resistance effectively university administrators must understand the nature and causes of resistance to change. Only by dealing effectively with resistance to change can organizational change be implemented successfully. This paper explores organizational change and the challenge it poses for universities. Because universities are slow to change due to maintaining a balance of tradition and change successful implementation of change will continue to be a challenge both now and in the future. The challenge of change is real but the task is not impossible. Historically, universities have met the challenges that faced them; they must be prepared to confront this challenge too.

Controversies exist regarding objective documentation of fatigue development with low-force contractions. We hypothesized that non-exhaustive, low-force muscle contraction may induce prolonged low-frequency fatigue (LFF) that in the subsequent recovery period is detectable by electromyography (EMG) and in particular mechanomyography (MMG) during low-force rather than high-force test contractions. Seven subjects performed static wrist extension at 10% maximal voluntary contraction (MVC) for 10 min (10%MVC10 min). Wrist force response to electrical stimulation of extensor carpi radialis muscle (ECR) quantified LFF. EMG and MMG were recorded from ECR during static test contractions at 5% and 80% MVC. Electrical stimulation, MVC, and test contractions were performed before 10%MVC10 min and at 10, 30, 90 and 150 min recovery. In spite of no changes in MVC, LFF persisted up to 150 min recovery but did not develop in a control experiment omitting 10%MVC10 min. In 5% MVC tests significant increase was found in time domain of EMG from 0.067+/-0.028 mV before 10%MVC10 min to 0.107+/-0.049 and 0.087+/-0.05 mV at 10 and 30 min recovery, respectively, and of the MMG from 0.054+/-0.039 ms(-2) to 0.133+/-0.104 and 0.127+/-0.099 ms(-2), respectively. No consistent changes were found in 80% MVC tests. In conclusion, non-exhaustive low-force muscle contraction resulted in prolonged LFF that in part was identified by the EMG and MMG signals.

The relation between lipid accumulation and influence of exercise on insulin sensitivity is not straightforward. A proper balance between lipid droplet synthesis, lipolysis, and oxidative metabolism would ensure low local intramyocellular fatty acid levels, thereby possibly protecting against lipotoxicity-associated insulin resistance. This study investigated whether the accumulation of triglycerides and lipid droplets in response to high availability of fatty acids after high-fat feeding would parallel the abundance of intramyocellular perilipin proteins, especially PLIN5. The effects on these variables after diet change or voluntary running exercise intervention in skeletal muscle were also investigated. During a 19-week experiment, C57BL/6J mice were studied in six different groups: low-fat diet sedentary, low-fat diet active, high-fat diet sedentary, high-fat diet active and two groups which were high-fat sedentary for nine weeks, after which divided into low-fat sedentary or low-fat active groups. Myocellular triglyceride concentration and perilipin protein expression levels were assessed. We show that, concurrently with impaired insulin sensitivity, the expression level of PLIN5 and muscular triglyceride concentration increased dramatically after high-fat diet. These adaptations were reversible after the diet change intervention with no additional effect of exercise. After high-fat diet, lipid droplets become larger providing more surface area for PLIN5. We suggest that PLIN5 is an important regulator of lipid droplet turnover in altered conditions of fatty acid supply and consumption. Imbalances in lipid droplet metabolism and turnover might lead to lipotoxicity-related insulin resistance. Copyright © 2014 Elsevier Inc. All rights reserved.

Yet many demographic, as well as economic and social factors, are making the task more difficult. Low birth rates, especially among non-Hispanic whites, along with high immigration rates, have increased the share of minority and non-English students in public schools. The rise in single-parent families has increased the number of poor students and migration from the cities to the suburbs has concentrated poor and minority students in inner city schools. These same children will make up a greater share of the future labor force. At the same time, the aging of the general population may lessen the commitment of homeowners- -whose taxes pay between 1/3 and 1/2 of education costs. The aging labor force may bring a shortage of qualified teachers, particularly in specialized subject areas. Poor and minority students generally have below average academic skills and are more likely to drop out of high school than non-minority students. However, the skills of American students rank below those of most other industrialized nations, calling into question the ability of Americans to succeed in an increasingly international economic system. How can schools be improved and minority student achievement be enhanced? Reforms of education finance systems, court-ordered integration, and stiffer requirements for teachers and for graduation from high school are among many attempts to meet the immense challenges faced by American schools.

Drylands are home to more than 38% of the world's population and are one of the most sensitive areas to climate change and human activities. This review describes recent progress in dryland climate change research. Recent findings indicate that the long-term trend of the aridity index (AI) is mainly attributable to increased greenhouse gas emissions, while anthropogenic aerosols exert small effects but alter its attributions. Atmosphere-land interactions determine the intensity of regional response. The largest warming during the last 100 years was observed over drylands and accounted for more than half of the continental warming. The global pattern and interdecadal variability of aridity changes are modulated by oceanic oscillations. The different phases of those oceanic oscillations induce significant changes in land-sea and north-south thermal contrasts, which affect the intensity of the westerlies and planetary waves and the blocking frequency, thereby altering global changes in temperature and precipitation. During 1948-2008, the drylands in the Americas became wetter due to enhanced westerlies, whereas the drylands in the Eastern Hemisphere became drier because of the weakened East Asian summer monsoon. Drylands as defined by the AI have expanded over the last 60 years and are projected to expand in the 21st century. The largest expansion of drylands has occurred in semiarid regions since the early 1960s. Dryland expansion will lead to reduced carbon sequestration and enhanced regional warming. The increasing aridity, enhanced warming, and rapidly growing population will exacerbate the risk of land degradation and desertification in the near future in developing countries.
Plants are permanently impacted by their environments, and their abilities to tolerate multiple fluctuating environmental conditions vary as a function of several genetic and natural factors. Over the past decades, scientific innovations and applications of the knowledge derived from biotechnological investigations to agriculture caused a substantial increase of the yields of many crops. However, due to exacerbating effects of climate change and a growing human population, a crisis of malnutrition may arise in the upcoming decades in some places in the world. So, effective, ethical and managerial regulations and fair policies should be set up and applied at the local and global levels so that Earth may fairly provide the food and living accommodation needed by its inhabitants. To save some energy consumption, electric devices (for e.g., smartphones, laptops, street lights, traffic lights, etc.) should be manufactured to work with solar energy, whenever available, particularly in sunny countries where sun is available most of the time. Such characteristic will save energy and make solar energy-based smartphones and laptops less cumbersome in terms of chargers and plugging issues.

Full Text Available Gameplay is commonly considered to be a voluntary activity. Game designers generally believe that voluntary gameplay is essentially different from mandatory gameplay. Such a belief may be a challenge for serious games, as instruction is usually mandatory. The article describes the outcomes of two experiments on the impact of voluntariness on the learning effect and enjoyment of a serious game. In the first experiment freedom of choosing to play a serious game was studied, with participants who had volunteered to participate. The results suggested that, contrary to the opinion of many game designers, being required to play a serious game does not automatically take the fun out of the game. The second experiment had voluntary participants and mandatory participants, who had to participate as part of a homework assignment. The outcomes show that mandatory participants enjoyed the game as much as the voluntary participants, even if they had to play the game for a minimum required time. These studies indicate that mandatory gameplay does not reduce enjoyment and learning effect.
Full Text Available Climate change represents a major global challenge, with a range of potential impacts on human health linked to the changing weather patterns, temperatures, more intense and frequent extreme weather events, changes in ecosystems, agriculture, and infrastructure. Climate change can multiply risks and existing health problems; it sets conditions under which health effects may occur, depending on population vulnerability and ability to adapt. In response to this global challenge, both mitigation and adaptation measures are needed. Europe is already experiencing impacts of the changing climate, and some regions are particularly vulnerable. From the public health perspective, adaptation to climate change means protection of a population from adverse health impacts, including effects of extreme temperatures (e.g. heat waves, emerging or re-emerging infectious diseases, as well as allergic diseases linked to the changing pollination seasons.
Emotional status and its brain bases change in a chronic pain patient and this change affects his/her decision making ability. Moreover, it is accepted that a mentally disturbed individual is not competent to make critical decisions. According to these bases, this article demonstrates that such patients are not entitled to request voluntary euthanasia.

Increasing geographical mobility and international travel augment the ease and speed by which infectious diseases can spread across large distances. It is therefore incumbent upon each state to ensure that immunisation programmes are effective and that herd immunity is achieved. Across Europe, a range of immunisation policies exist: compulsion, the offer of financial incentives to parents or healthcare professionals, social and professional pressure, or simply the dissemination of clear information and advice. Until recently, immunisation against particular communicable diseases was compulsory in Italy. The Italian National Vaccination Plan (NVP) (2005-7) paved the way for regions to suspend the sanctions associated with compulsory vaccinations for children when certain criteria are met--for example when immunisation coverage is high and when effective monitoring/surveillance systems are in place--and thus marked a milestone in the move from compulsory to voluntary immunisation. The forthcoming NVP for 2008-10 confirms the liberal approach to vaccination in Italy as it entrusts to the regions responsibility for the achievement and maintenance of herd immunity. This paper reviews the arguments for and against compulsory and voluntary immunisation in relation to the Italian NVP (2005-7) and in the context of the diverse immunisation policies that exist across Europe. It concludes with cautious support for the NVP and an associated shift from compulsory to voluntary immunisation in Italy, and draws similarities between issues concerning regional variation in immunisation policy in Italy and national variation in immunisation policy across Europe and beyond.

Try as it might, wildlife management cannot make wild living things adapt to climate change. Management can, however, make adaptation more or less likely. Given that policy is a rule set for action, policy will play a critical role in societyâs efforts to help wildlife cope with the challenge of climate change. To be effective, policy must provide clear goals and be...

Full Text Available Doubtless to say, the contribution of reading skill to first and second language acquisition is enormous. From one‟s speaking and writing we can more or less conclude how much s/he has read. We can list the characteristics of good readers as follows: rich vocabulary knowledge advanced reading comprehension, accurate grammar usage, broad general knowledge, correct spelling and punctuation, writing ability, and so on. If reading is so powerful, why cannot we promote reading books in our society, particularly among young people? The fact that we are imposed to read books which we think are necessary or compulsory rather than the ones which we would like to read voluntarily, is the main reason why many of us are not able to develop a life-time reading habit. Since compulsory books, such as teacher-selected books are outside one‟s interest; they are destined to be forgotten sometime, or they suffer form shallow reading, or they are mostly returned to their place on the shelf after browsing the initial pages. However, if people of all ages, especially children would read self-selected books they enjoy, they would be surprised to notice the great change inside them. Therefore, the purpose of this study is to revitalize free voluntary reading by referring to Krashen‟s well-known hypotheses. Also, it aims to revive the reader‟s belief in free voluntary reading with theoretical and practical examples

Climate change is one of the defining challenges of the 21st century, but is no longer a matter of just scientific concern. It encompasses economics, sociology, global politics as well as national and local politics, law, health and environmental security, etc. The challenge of facing the impacts of climate change is often framed in terms of two potential paths that civilization might take: mitigation and adaptation. On the one hand, mitigation involves reducing the magnitude of climate change itself and is composed of emissions reductions and geoengineering. On the other hand and by contrast, adaptation involves efforts to limit our vulnerability to climate change impacts through various measures. It refers to our ability to adjust ourselves to climate change -including climate variability and extremes, to moderate potential damage, to take advantage of opportunities, or to cope with the consequences. Therefore, we are now faced with a double challenge: next to deep cuts in greenhouse gas emissions, we also need to adapt to the changing climate conditions. The use of satellites to monitor processes and trends at the global scale is essential in the context of climate change. Earth Observation has the potential to improve our predictive vision and to advance climate models. Space sciences and technologies constitute a significant issue in Education and Public Awareness of Science. Space missions face the probably largest scientific and industrial challenges of humanity. It is thus a fact that space drives innovation in the major breakthrough and cutting edge technological advances of mankind (techniques, processes, new products, … as well as in markets and business models). Technology and innovation is the basis of all space activities. Space agencies offer an entire range of space-related activities - from space science and environmental monitoring to industrial competitiveness and end-user services. More specifically, Earth Observation satellites have a unique

Dissemination and scale up of voluntary medical male circumcision (VMMC) programs is well supported by evidence that VMMC reduces HIV risk in populations with high HIV prevalence and low rates of circumcision, as is the case in Zambia. At both individual and population levels, it is important to understand what stages of change for VMMC are associated with, especially across cultures. This study evaluated VMMC knowledge, misinformation, and stages of change for VMMC of uncircumcised men and boys (over 18 years), as well as the concurrent relationship between VMMC stages of change and sexual risk behaviors. Uncircumcised (N = 800) adult men and boys (over 18) were screened and recruited from urban community health centers in Lusaka, Zambia, where they then completed baseline surveys assessing knowledge, attitudes, HIV risk behaviors, and stages of change for VMMC. A series of analyses explored cross-sectional relationships among these variables. VMMC was culturally acceptable in half of the sample; younger, unmarried, and more educated men were more ready to undergo VMMC. Stage of change for VMMC was also related to knowledge, and those at greater HIV risk reported greater readiness to undergo VMMC. Efforts to increase VMMC uptake should address the role of perceived HIV risk, risk behaviors, readiness, accurate knowledge, cultural acceptance, and understanding of the significant degree of HIV protection conferred as part of the VMMC decision making process. These results support incorporating comprehensive HIV risk reduction in VMMC promotion programs.
Full Text Available The role of e-learning technologies entirely depends on the acceptance and execution of required-change in the thinking and behaviour of the users of institutions. The research are constantly reporting that many e-learning projects are falling short of their objectives due to many reasons but on the top is the user resistance to change according to the digital requirements of new era. It is argued that the suitable way for change management in e-learning environment is the training and persuading of users with a view to enhance their digital literacy and thus gradually changing the users’ attitude in positive direction. This paper discusses change management in transition to e-learning system considering pedagogical, cost and technical implications. It also discusses challenges and opportunities for integrating these technologies in higher learning institutions with examples from Turkey GATA (Gülhane Askeri Tıp Akademisi-Gülhane Military Medical Academy.

From climate change to hydraulic fracturing, and from drinking water safety to wildfires, environmental challenges are changing. The United States has made substantial environmental protection progress based on media-specific and single pollutant risk-based frameworks. However, today’s environmental problems are increasingly complex and new scientific approaches and tools are needed to achieve sustainable solutions to protect the environment and public health. In this article, we present examples of today’s environmental challenges and offer an integrated systems approach to address them. We provide a strategic framework and recommendations for advancing the application of science for protecting the environment and public health. We posit that addressing 21st century challenges requires transdisciplinary and systems approaches, new data sources, and stakeholder partnerships. To address these challenges, we outline a process driven by problem formulation with the following steps: a) formulate the problem holistically, b) gather and synthesize diverse information, c) develop and assess options, and d) implement sustainable solutions. This process will require new skills and education in systems science, with an emphasis on science translation. A systems-based approach can transcend media- and receptor-specific bounds, integrate diverse information, and recognize the inextricable link between ecology and human health.

Saccades are fast eye movements that reorient gaze. They can be performed voluntarily-for example, when viewing a scene-but they can also be triggered in reaction to suddenly appearing targets. The generation of these voluntary and reactive saccades have been shown to involve partially different cortical pathways. However, saccades of either type confront the visual system with a major challenge from massive image motion on the retina. Despite the fact that the whole scene is swept across the retina, a saccade usually does not elicit a percept of motion. This saccadic omission has been linked to a transient decrease of visual sensitivity during the eye movement, a phenomenon called saccadic suppression. A passive origin of saccadic suppression based on temporal masking has been proposed as well as an active central process that inhibits visual processing during the saccade. The latter one would need to include an extraretinal signal, which is generated already during saccade preparation. Since saccade generation differs for voluntary and reactive saccades, timing and nature of this extraretinal signal as well as its impact on visual sensitivity might also differ. We measured detection thresholds for luminance stimuli that were flashed during voluntary and reactive saccades and during fixation. Detection thresholds were higher during voluntary than during reactive saccades such that suppression appeared stronger during voluntary saccades. Stronger suppression in voluntary saccades could arise from a stronger extraretinal signal that activates suppression or could indicate that a suppression underlying process itself partially differs between voluntary and reactive saccades.

This article explores the concept of professionalism as it relates to social change and social accountability, and expands on them in the light of global environmental changes. Professionalism in medicine includes concepts of altruism, service, professional knowledge, self-regulation and autonomy. Current dialogues around social accountability suggest that medical schools should re-orientate their strategy and desired education, research and service outcomes to the health needs of the communities they serve.This article addresses the following questions: • How do we reconcile ideas of medical professionalism with the demands of creating a more equal, just, sustainable and socially inclusive society? • What new challenges do or will we face in relation to environmental degradation, biodiversity loss, ecosystem health and climate change? • How can medical schools best teach social and environmental responsiveness within a framework of professionalism? • How do medical schools ensure that tomorrow's doctors possess the knowledge, skills and attitude to adapt to the challenges they will face in future roles?We offer ideas about why and how medical educators can change, recommendations to strengthen the teaching of professionalism and social accountability and suggestions about the contribution of an emerging concept, that of "environmental accountability".

Climate change is one of the greatest public health challenges of our time. Despite some inherent uncertainties in making predictions about climate change, there is wide scientific consensus that global warming is occurring; that it is largely due to manmade greenhouse gas emissions; and that it will have substantial health implications for the future. The predicted health impacts of climate change are now clearer for New Zealand, and general practitioners can take action to mitigate these impacts and adapt to the future environment. Actions required involve a combination of 'top-down' and 'ground-up' approaches; effective leadership and policy from our health institutions and, importantly, individual practice initiatives that transform these goals into practical outcomes.

It has been long recognised that dispersal is an important life-history trait that plays a key role in the demography and evolution of populations and species. This then suggests that dispersal play a central role in the response of populations and species to ever-increasing global change, including climate change, habitat loss and fragmentation, and biological invasions. During a symposium held at Lund University (Sweden), the causes and consequences of dispersal were discussed, and here we provide an overview of the talks. As the discussions often gravitated towards the role and our understanding of dispersal in a changing world and given the urgent challenges posed by it, we place this overview in the context of global change. We draw and discuss four conclusions: (i) methodological advances provide opportunities for improved future studies, (ii) dispersal distances can be much greater than previously thought (examples in plants and vertebrates), but also much more restricted (examples in micro-organisms), (iii) dispersal is more dynamic than we often care to admit (e.g. due to individual variation, effects of parasites, variation in life history, developmental and evolutionary responses, community impacts), (iv) using results of dispersal research for detailed prediction of outcomes under global change is currently mostly out of reach - nevertheless, that should not stop us from showing the many negative consequences of global change, and how dispersal is often a limiting factor in adapting to this.
This book published by the Energy Science Center (ESC) at the Swiss Federal Institute of Technology (ETH) in Zurich presents a wide selection of reports on how the challenge of dealing with climate change can be met. The 69 reports included cover a wide range of topics ranging from traffic modelling, biofuels and electrification of power trains, through demand-side management, electricity production and distribution and life cycle assessment, to the integration of wind power and renewable energy technologies. Also, climate policy matters are dealt with as are nano-technology applications in the energy area and the integration of energy conversion and production processes and waste management.
The dramatic changes occurring in the age structure of the Thai population make providing healthcare services for the elderly a major challenge for decision makers. Because the number of the elderly will be increasing, together with the number of retired workers, under the Social Health Insurance (SHI) scheme, there will be the unmet needs for healthcare use after retirement. The SHI scheme does not cover workers after retirement unless they could use free healthcare for the elderly. In addition, the government budget is tight regarding the support of universal healthcare and long-term care services for all of the elderly. Therefore, the government could support retired workers who have the ability to pay by facilitating voluntary health insurance. The main objectives of the present study are to analyze the characteristics of workers that need health insurance after retirement and to identify the factors explaining healthcare use to offer healthcare services to meet the workers' needs and expectations. Four hundred insured workers under the Social Health Insurance (SHI) Scheme in Thailand were interviewed using a structured questionnaire. The Anderson-Newman model of healthcare use is the conceptual framework used in this study to understand the factors that explain healthcare use patterns of workers. Multiple regressions are employed extensively to evaluate the variables that predict healthcare use. According to the survey, a person that purchases voluntary health insurance is likely to be female, have a higher personal income, and healthy. The characteristics related to healthcare use were poor health status, a high personal income, and peeople afflicted by chronic illness. There is a gap between healthcare service use and the demand for voluntary health insurance. People that have a high income are more likely to purchase voluntary health insurance, while people in worse health and afflicted by chronic illness may have greater difficulty purchasing voluntary

They are sensitive to temperature and moisture changes and adjust their mass balances accordingly. By doing so they interact with their substratum, the geological basement and they produce characteristic imprints of their presence, their variability and their disappearance. In glacial geology and paleoglaciology such imprints of former glaciers are carefully recorded, mapped and, hopefully, dated in order to obtain amplitude and periodicity records of their changes - as forced by changing climate, as we believe. In the upcoming lectures three aspects will be discussed: the last glaciation in the Swiss Alps. A reconstruction is shown based on fieldwor...

This article focuses on two recurrent themes in the study of acculturation in adolescence that challenge progress of the field. First, we often work with low-dimensional, trait-like models of acculturation that cannot deal with modern types of acculturation that are often characterized by multidimensionality and domain specificity. Second, acculturative change in adolescence is undertheorized and there is a need to integrate developmental tasks and models of acculturation. It is argued that approaches that have been adopted in the study of identity (with their models that range from generalized traits to situated approaches and their adoption of both quantitative and qualitative methods) are highly suitable for the study of acculturation. A more contextualized approach would also facilitate the study of the interaction of contextual conditions and acculturative changes in adolescence.

Clinical engineering is at a strategic inflection point. Technical, economic, regulatory, and cultural dynamics are at work shaping the future of healthcare delivery. As the nature of healthcare delivery is transformed by these forces, the types and mix of technology management and support services needed by the industry are changing significantly. Clinical engineering has a relatively short opportunity to adopt a service model that will meet these changing needs. Delay or failure to adopt an effective service model as we pass through the inflection point will result in a diminished role for clinical engineering in healthcare technology management as other technical professionals move in to fill the need. The question is: will clinical engineering rise to the challenge?

This study investigated the effect of living (summer vs. winter) and working (morning vs. afternoon) in a hot environment on markers of immune function and forearm strength. Thirty-one healthy male gas field employees were screened before (between 05:30 and 07:00) and after their working day (between 15:30 and 17:00) during both seasons. Body core temperature and physical activity were recorded throughout the working days. The hot condition (i.e. summer) led a higher (p≤0.05) average body core temperature (~37.2 vs. ~37.4 °C) but reduced physical activity (-14.8%) during the work-shift. Our data showed an increase (p≤0.05) in lymphocyte and monocyte counts in the summer. Additionally, work-shift resulted in significant (p≤0.001) changes in leukocytes, lymphocytes and monocytes independently of the environment. Handgrip (p=0.069) and pinch (p=0.077) forces tended to be reduced from pre-to post-work, while only force produced during handgrip manoeuvres was significantly reduced (p≤0.05) during the hot compared to the temperate season. No interactions were observed between the environment and work-shift for any marker of immune function or forearm strength. In summary, working and living in hot conditions impact on markers of immune function and work capacity; however by self-regulating energy expenditure, immune markers remained in a healthy reference range.

To examine how the development of obesity and the associated insulin resistance affect bone structural and material properties, and bone formation and resorption markers in the Otsuka Long-Evans Tokushima Fatty (OLETF) rat model. This was a 36-week study of sedentary, hyperphagic, male OLETF rats (OLETF-SED), exercise-treated OLETF rats (OLETF-EX) and sedentary non-hyperphagic controls (LETO-SED) with data collection at 13, 20, and 40 weeks of age (n = 5-8 animals per group per timepoint). Body mass and fat (%) were significantly greater in OLETF-SED versus controls. OLETF-SED were insulin resistant at 13 and 20 weeks, with overt diabetes by 40 weeks. At 13weeks, OLETF-SED had lower total body BMC and BMD and serum P1NP compared with LETO-SED. Differences in total body BMC and BMD between OLETF-SED and LETO-SED persisted at 20 weeks, with reductions in total and cortical BMD of the tibia. OLETF-SED also had lesser femur diameter, cross-sectional area, polar moment of area, and torque at fracture than LETO-SED. By 40 weeks, OLETF-SED had elevated bone resorption and reduced intrinsic bone strength. OLETF-EX did not show the excessive weight gain, obesity, insulin resistance or diabetes observed in OLETF-SED. OLETF-EX had greater BMD than OLETF-SED, and structural and material properties of the femur were significantly increased in OLETF-EX relative to OLETF-SED and LETO-SED. The negative skeletal effects of excessive adiposity and insulin resistance were evident early in the progressive obesity with lasting negative impacts on intrinsic and extrinsic bone strength. Exercise protected against obesity-associated skeletal changes with marked benefits on the biomechanical properties of bone. Copyright © 2015 Elsevier Inc. All rights reserved.
Full Text Available One of the numerous challenges in the educational processes is teacher training, particularly in the framework of neo-liberal global societies ruled by the competitiveness of regular and continuous education programs in teacher training. It is a matter of concern and, therefore, a matter of analysis, if we consider the deep impact in all contexts. Accordingly, this paper discusses the situation from a descriptive perspective as a basic requirement to go beyond the analysis on the urgency of having clear educational policies related to the variety and quality of curricular programs; and, above all, a strong awareness from teacher trainers to see themselves as the critical creative mass from which change can be made, based on socially human proposals.

Several neurodevelopmental disorders are associated with resistance to change and challenging behaviours - including temper outbursts - that ensue following changes to routines, plans or expectations (here, collectively: expectations). Here, a change signalling intervention was tested for proof of concept and potential practical effectiveness. Twelve individuals with Prader-Willi syndrome participated in researcher- and caregiver-led pairing of a distinctive visual-verbal signal with subsequent changes to expectations. Specific expectations for a planned subset of five participants were systematically observed in minimally manipulated natural environments. Nine caregivers completed a temper outburst diary during a four week baseline period and a two week signalling evaluation period. Participants demonstrated consistently less temper outburst behaviour in the systematic observations when changes imposed to expectations were signalled, compared to when changes were not signalled. Four of the nine participants whose caregivers completed the behaviour diary demonstrated reliable reductions in temper outbursts between baseline and signalling evaluation. An active control group for the present initial evaluation of the signalling strategy using evidence from caregiver behaviour diaries was outside the scope of the present pilot study. Thus, findings cannot support the clinical efficacy of the present signalling approach. Proof of concept evidence that reliable pairing of a distinctive cue with a subsequent change to expectation can reduce associated challenging behaviour is provided. Data provide additional support for the importance of specific practical steps in further evaluations of the change signalling approach. Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available Accumulating evidence indicates that regular physical exercise benefits health in part by counteracting some of the negative physiological impacts of stress. While some studies identified reductions in some measures of acute stress responses with prior exercise, limited data were available concerning effects on cardiovascular function, and reported effects on HPA axis responses were largely inconsistent. Given that exposure to repeated or prolonged stress is strongly implicated in the precipitation and exacerbation of illness, we proposed the novel hypothesis that physical exercise might facilitate adaptation to repeated stress, and subsequently demonstrated significant enhancement of both HPA axis (glucocorticoid and cardiovascular (tachycardia response habituation to repeated noise stress in rats with long-term access to running wheels compared to sedentary controls. Stress habituation has been attributed to modifications of brain circuits, but the specific sites of adaptation and the molecular changes driving its expression remain unclear. Here, in situ hybridization histochemistry was used to examine regulation of select stress-associated signaling systems in brain regions representing likely candidates to underlie exercise-enhanced stress habituation. Analyzed brains were collected from active (6 weeks of wheel running and sedentary rats following control, acute, or repeated noise exposures that induced a significantly faster rate of glucocorticoid response habituation in active animals but preserved acute noise responsiveness. Nearly identical experimental manipulations also induce a faster rate of cardiovascular response habituation in exercised, repeatedly stressed rats. The observed regulation of the corticotropin-releasing factor and brain-derived neurotrophic factor systems across several brain regions suggests widespread effects of voluntary exercise on central functions and related adaptations to stress across multiple response

Intense erosion processes are widespread in the Mediterranean region, and include sheet wash erosion, rilling, gullying, shallow landsliding, and the development of large and active badlands in both subhumid and semi-arid areas. This review analyses the main environmental and human features related to soil erosion processes, and the main factors that explain the extreme variability of factors influencing soil erosion, particularly recent land use changes. The importance of erosion in the Mediterranean is related to the long history of human activity in a region characterized by low levels of annual precipitation, the occurrence of intense rainstorms and long-lasting droughts, high evapotranspiration, the presence of steep slopes and the occurrence of recent tectonic activity, together with the recurrent use of fire, overgrazing and farming. These factors have resulted in a complex landscape in which intensification and abandonment, wealth and poverty can co-exist. The changing conditions of national and international markets and the evolution of population pressure are now the main drivers explaining land use changes, including farmland abandonment in mountain areas, the expansion of some subsidized crops to marginal lands, and the development of new terraces affected by landslides and intense soil erosion during extreme rainstorm events. The occurrence of human-related forest fires affecting thousands of hectares each year is a significant problem in both the northern and southern areas of the Mediterranean basin. Here, we highlight the rise of new scientific challenges in controlling the negative consequences of soil erosion in the Mediterranean region: 1) to reduce the effects and extent of forest fires, and restructure the spatial organization of abandoned landscapes; 2) to provide guidance for making the EU agricultural policy more adapted to the complexity and fragility of Mediterranean environments; 3) to develop field methods and models to improve the
Full Text Available Synthesis and New Conception of North Sea Research (SYCON is the title of a German project carried out from 1998-2000 under the leadership of Hamburg University 1. It was accompanied by an international advisory board and covered North Sea issues as well as the general challenges to shelf sea research and sustainable management under global change. Particular emphasis was placed on the interdisciplinary analysis of comprehensive areas of knowledge: the data situation, understanding of processes, model development, instruments and methods, understanding of the system. Based onthis, perspectives for future North Sea research were developed. The project produced a synthesis report, eleven monodisciplinaryreports and an illustrated brochure for the general public (see Annex 1, this paper, p. 258.1The SYCON Project was carried out with support of the German Federal Ministry of Education and Research under GrantNo. 03F0215A. This article is based on the SYCON Synthesis Report (Südermann et al. 2001.
Our world is becoming increasingly global. This may sound like a clich'e, yet it is true nonetheless, and poses unprecedented challenges for graduate education. For the new generation of researchers, teachers and professionals to be successful they must be prepared in more than the content area of their chosen field. They must also acquire proficiency in global awareness, cultural literacy, multicultural teamwork and language facility. These global skill sets form the basis for effective multicultural collaboration and will become increasingly important even for those who do not intend to study or work abroad. Knowledge has become more portable in the internet age; large data bases and reports can be accessed in real time from various locations around the globe; information is exchanged in multifaceted knowledge networks; collaborative research takes place within and outside of the traditional venue of the research university in the private sector, research institutes, and associations; research networks span multiple disciplines as progress invariably occurs at the intersection of previously discrete fields of inquiry. Global collaboration thus is no longer dependent on the physical proximity of collaborators but can take place anywhere any time. This then requires yet another set of skills, namely the ability to adapt to change, exhibit flexibility and transfer skills to a range of contexts and applications. Effective graduate education must address these realities and expose students to learning opportunities that will enable them to acquire these much needed global skills sets.

The United States is in the midst of a continental-scale, multi-year water-resources experiment, in which society has not defined testable hypotheses or set the duration and scope of the experiment. What are we doing? We are expanding population at two to three times the national growth rate in our most water-scarce states, in the southwest, where water stress is already great and modeling predicts decreased streamflow by the middle of this century. We are expanding irrigated agriculture from the west into the east, particularly to the southeastern states, where increased competition for ground and surface water has urban, agricultural, and environmental interests at odds, and increasingly, in court. We are expanding our consumption of pharmaceutical and personal care products to historic high levels and disposing of them in surface and groundwater, through sewage treatment plants and individual septic systems that were not designed to treat them. These and other examples of our national-scale experiment are likely to continue well into the 21st century. This experiment and related challenges will continue and likely intensify as non-climatic and climatic factors, such as predicted rising temperature and changes in the distribution of precipitation in time and space, continue to develop.

Cough is normally referred to a reflex mediated by control centres in the respiratory areas of the brainstem. However, there is much experimental information that indicates that human cough is under voluntary control and that higher centres such as the cerebral cortex have an important role in both initiating and inhibiting cough. Studies on acute cough associated with common cold, and capsaicin induced cough have demonstrated that human cough can be voluntarily inhibited and often abolished. Further evidence for some role of consciousness in the control of cough comes from studies that show that cough is inhibited or abolished during sleep and with light anaesthesia. This paper discusses the historical development of the brainstem 'cough centre' and discusses the experimental evidence on the voluntary control of cough in man. A cough model demonstrating the voluntary and reflex control of cough in man is proposed. A hypothesis is proposed that cough associated with common cold is a mixture of both reflex and voluntary cough. Copyright 2002 Published by Elsevier Science Ltd.

In order to complete the clean coal technology mission it will be necessary to determine CCT`s role in the restructured electricity industry and develop a strategy to promote that role. First, one must understand where the industry is headed and how clean coal technology fits into that future. Then, one needs to develop a strategy for getting from here to there, from where CCT is today to where it must be in five, ten or twenty years to be a viable option for decision-makers. Coal makes sense for the United States for several important reasons, not the least of which is its abundance here. It also makes sense in terms of its economic impact on large areas of the nation. And if coal makes sense, especially economically, then clean coal technology makes even more sense because of its potential to capitalize on this abundant resource in an environmentally friendly manner. But after nearly thirty years of involvement in the political world at all levels from Washington, D.C. to Washington, Indiana, the author has learned the hard way that ``common sense`` does not always, or even often, carry the day in the policymaking process. He believes that the future of clean coal technology hinges on the ability in the next few months and years to mobilize all those who favor that technology to move forward in a cohesive and coordinated effort to affect the policymaking and political process and thereby promote and accelerate CCT development. If this can be done, then the nation will be well on the way to completing the clean coal technology mission and meeting the challenge of change.

The Voluntary Reporting Program for greenhouse gases is part of an attempt by the U.S. Government to develop innovative, low-cost, and nonregulatory approaches to limit emissions of greenhouse gases. It is one element in an array of such programs introduced in recent years as part of the effort being made by the United States to comply with its national commitment to stabilize emissions of greenhouse gases under the Framework Convention on Climate Change. The Voluntary Reporting Program, developed pursuant to Section 1605(b) of the Energy Policy Act of 1992, permits corporations, government agencies, households, and voluntary organizations to report to the Energy Information Administration (EIA) on actions taken that have reduced or avoided emissions of greenhouse gases.

This report analyses the consequences of climate change and global warming for international politics in general and international security in particular. The report focuses on whether and in what way climate change may alter the conditions of international security. From this perspective, the initial effects of climate change will vary according to existing economic, political and social structures in different world regions. Organised violence is more likely in regions with weak states and conflictual inter-state dynamics than in those characterised by co-operative relations. In the short- to medium term, climate change is unlikely to alter the constitutive structures of international security. However, depending on the severity of climate change, these conditions may change over the long term. Such changes will probably depend on the secondary effects that change has on the world and regional economies. Climate change is unlikely to lead to an increase in conflicts in the short- to medium term, but a long-term development marked by unmitigated climate change could very well have serious consequences for international security. The report argues that, although necessary, mitigation and adaptation measures may have consequences for international politics. These are due to the changes in social and political systems that they entail.

Social marketing applies commercial sector ideas to programs to change behavior. It involves a mindset that is customer-focused; a process that starts with customers and continually returns to them for validation; and concepts to make change happen. Customer behavior models guide strategy. One useful model is based on stages of change and four behavioral influences: perceived benefits, perceived costs, the influence of others, and perceived behavioral control.

As a large northern country, Canada will change significantly as a result of climate change. Global warming is expected to cause diminutions of snow and ice changes in the Arctic, as well as changes to glaciers, and the mountain snowpacks that feed rivers, and provide sources of fresh water. This book argued that the effects of global warming have been apparent in Canada for many years. Water levels in lakes and rivers have been falling, and a thawing permafrost has led to difficulties in building and maintaining winter roads in the far north. Disturbances such as the mountain pine beetle (MPB) infestation in British Columbia have also been attributed to global warming, the beetles are only killed by cold weather. The book also considered Canada's current climate change policies, and discussed attempts to arrive at meaningful and effective strategies. 30 refs.

Land-change science has emerged as a foundational element of global environment change and sustainability science. It seeks to understand the human and environment dynamics that give rise to changed land uses and covers, not only in terms of their type and magnitude but their location as well. This focus requires the integration of social, natural, and geographical information sciences. Each of these broad research communities has developed different ways to enter the land-change problem, each with different means of treating the locational specificity of the critical variables, such as linking the land manager to the parcel being managed. The resulting integration encounters various data, methodological, and analytical problems, especially those concerning aggregation and inference, land-use pixel links, data and measurement, and remote sensing analysis. Here, these integration problems, which hinder comprehensive understanding and theory development, are addressed. Their recognition and resolution are required for the sustained development of land-change science.
Full Text Available The evidence about the effectiveness of behaviour change approaches—what works and what does not work—is unclear. What we do know is that single interventions that target a specific behavioural risk have little impact on the determinants that actually cause poor health, especially for vulnerable people. This has not prevented health promoters from continuing to invest in behaviour change interventions which are widely used in a range of programs. The future of behaviour change and health promotion is through the application of a comprehensive strategy with three core components: (1 a behaviour change approach; (2 a strong policy framework that creates a supportive environment and (3 the empowerment of people to gain more control over making healthy lifestyle decisions. This will require the better planning of policy interventions and the coordination of agencies involved in behaviour change and empowerment activities at the community level, with government to help develop policy at the national level.

Growing concern about biodiversity loss underscores the need to quantify and understand temporal change. Here, we review the opportunities presented by biodiversity time series, and address three related issues: (i) recognizing the characteristics of temporal data; (ii) selecting appropriate statistical procedures for analysing temporal data; and (iii) inferring and forecasting biodiversity change. With regard to the first issue, we draw attention to defining characteristics of biodiversity time series—lack of physical boundaries, uni-dimensionality, autocorrelation and directionality—that inform the choice of analytic methods. Second, we explore methods of quantifying change in biodiversity at different timescales, noting that autocorrelation can be viewed as a feature that sheds light on the underlying structure of temporal change. Finally, we address the transition from inferring to forecasting biodiversity change, highlighting potential pitfalls associated with phase-shifts and novel conditions. PMID:23097514

The United States Global Change Research Program (USGCRP) is a confederation of the research arms of 13 Federal departments and agencies. Its mission is to build a knowledge base that informs human responses to climate and global change through coordinated and integrated Federal programs of research, education, communication, and decision support. USGCRP has supported several initiatives to promote better understanding of climate change impacts on health, support responses, and build on the progress of the 2014 National Climate Assessment. Most recently, USGCRP released a new report, "The Impacts of Climate Change on Human Health: A Scientific Assessment". This presentation will provide an overview of USGCRP, highlight the importance of assessments, and introduce ways in which assessment findings and underlying data can be translated into critical tools to build resilience.

The aim of the present study was to describe personnel's attitudes to change processes between a regional hospital and the primary health care centre as well as investigate these results with regards to theories pertaining to change and leading change. Leadership has three crucial dimensions: focusing on personnel, results/key processes and the ethical base of activities. A survey was conducted in 2003 using a comprehensive questionnaire. The total sample consisted of the personnel (n = 899) at the two organizations (answering rate was 68.8%). The data were analysed descriptively. Approximately two-thirds of the respondents understood why the merger was occurring. Only one-third expressed that they had received sufficient information regarding the merger. In total 67% felt that the merger would create conflict while approximately one-fourth expressed uncertainty. Despite such negative responses, approximately two-thirds felt there were advantages to the merger. Significant differences were seen between the groups. In times of change personnel expect leaders to focus on dialogue with their personnel and to anchor the vision of the change process amongst the personnel. By identifying the 'prison of thought' and creating an atmosphere where reflection and discussion are valued the nurse leader can help prevent resistance to change.

Full Text Available Using U.S. Census data from 1990 to 2010, this paper examines Hmong Americans’ language use, English language ability, school attendance, high school dropout rate, and educational attainment. The data reveal significant improvements in Hmong Americans’ English languageability, attendance at higher levels of education, and higher education completion. The data also show that there are differences between states, between males and females, and between agecohorts with respect to certain educational outcomes. Additionally, the gap between Hmong females and males in terms of high school dropouts and educational attainment has narrowed considerably. Implications of these findings are discussed and consideration given to some of the persistent structural challenges that Hmong American students continue to face in K-12 public schools.

Full Text Available China is one of the largest countries in the world with nearly 20% of the world’s population. There have been significant improvements in economy, education and technology over the last three decades. Due to substantial investments from all levels of government, the public health system in China has been improved since the 2003 severe acute respiratory syndrome (SARS outbreak. However, infectious diseases still remain a major population health issue and this may be exacerbated by rapid urbanization and unprecedented impacts of climate change. This commentary aims to explore China’s current capacity to manage infectious diseases which impair population health. It discusses the existing disease surveillance system and underscores the critical importance of strengthening the system. It also explores how the growing migrant population, dramatic changes in the natural landscape following rapid urbanization, and changing climatic conditions can contribute to the emergence and re-emergence of infectious disease. Continuing research on infectious diseases, urbanization and climate change may inform the country’s capacity to deal with emerging and re-emerging infectious diseases in the future.

Ever since the 2003 heat wave that caused 70,000 heat deaths, the dramatic consequences of climate change and rising temperatures in Europe have become an intensively researched topic. During heat waves, the older urban adult population is at highest risk. The STOPHOT project is the first investigation in Austria to establish a comprehensive knowledge base on heat perception, awareness of heat risks and adaptive/coping behaviours among older adults. The main research questions include: (1) Does climate change endanger the chances of successful ageing in urban areas? (2) How do age, social inequalities and the living environment intersect with environmental stressors in affecting successful ageing? (3) Which heat adaption strategies do older adults deploy and to what extent can they mediate heat stress in an effort to increase chances of successful ageing under the conditions of climate change? The results indicate that climate change and rising temperatures are in fact one important determinant of whether and how an older person can maintain well-being in later life. Older adults (> 65 years) with a low socio-economic status and poor health conditions, who tend to be socially isolated, are most at risk. However, no 'heat island effect' of the residential environment could be found. How much a person suffers from heat stress is highly dependent on the adaption strategies deployed. Adaption strategies of older urban residents mostly centred on body-related measures, such as drinking more or wearing lighter clothes, and indoor-centred measures, particularly avoiding the outdoors.

The combination of genetic and environmental factors determines the individual vulnerability for excessive ethanol intake, possibly leading to dependence. The environmental influences early in life represent examples of determinant factors for adult behaviour and can be protective as well as risk factors. Maternal separation is one model to examine the long-term consequences of early environmental experiences on neurochemistry and behaviour, including drug-taking behaviour in experimental animals. In the present review, findings from studies using repeated short and prolonged periods of maternal separation, with emphasis on effects on voluntary ethanol intake in rats with or without a genetic predisposition for high voluntary ethanol intake, are summarized. Despite some contradictory results, the general picture emerging shows that short periods of maternal separation during the postnatal period result in a lower adult voluntary ethanol intake in male rats. Prolonged periods of maternal separation were found to induce a high voluntary ethanol intake in male rats, including rats with a genetic predisposition for high ethanol intake. Results from the literature also show that changes were not just related to time of separation but were also related to the degree of handling. Interestingly, in terms of voluntary ethanol intake, female rats were generally not affected by postnatal maternal separation. The reasons for these sex differences need further investigation. In terms of neurobiological consequences of maternal separation, conclusive data are sparse and one of the future challenges will, therefore, be to identify and characterize underlying neurobiological mechanisms, especially in the individual animal.
Most likely, past climate could not tell us much about the future. Large-scale climate models are not the best tool to tell us how tomorrow's infrastructure should be built. We must instead teach us new ways of using insecure information about the future - if we are to avoid getting behind in adapting to climate change. 'A user-defined approach to utilize climate change information in local implementation of national construction standards (RECON)' is an interdisciplinary pilot project undertaken as a collaboration between the Nansen Environmental and Remote Sensing Center (NERSC), Bjerknes Centre for Climate Research, Geophysical Institute, Uni Research at the University of Bergen, Norconsult, Norwegian School of Economics and Business Administration (SNF), Polar AS, Bergen Municipality and the University of Pretoria in South Africa.

There is significant personal injury risk associated with the provision of high-quality healthcare. The magnitude of this risk, combined with the possibility that it can often go underappreciated by caregivers and the organizations they work for, might help explain why the health sector has largely missed out on the benefits of an overall declining trend in injury rates. Despite covering two very different topics in their lead papers, Shamian and El-Jardali and Clements, Dault and Priest present a surprising degree of overlap in relation to what might help enable effective workplace change. Leadership, role clarity, trust, respect, values and workplace culture are all viewed as key enablers of effective teamwork by Clements, Dault and Priest. They could also be considered required ingredients of successful workplace health initiatives, as discussed by Shamian and El-Jardali. A lot of background and positional work regarding teamwork and healthy workplaces exists, but this has not necessarily translated into front-line change. These authors have done an excellent job of pointing out the potential benefits of workplace changes. What is needed now is for someone to take the lead in developing, implementing and evaluating these changes. The adult human form is an awkward burden to lift or carry. Weighing up to 200 pounds or more, it has no handles, it is not rigid, and it is susceptible to severe damage if mishandled or dropped. When lying in bed, a patient is placed inconveniently for lifting and the weight and placement of such a load would be tolerated by few industrial workers.

Cities play a prominent role in our economic development as more than 80 % of the gross world product (GWP) comes from cities. Only 600 urban areas with just 20 % of the world population generate 60 % of the GWP. Rapid urbanization, climate change, inadequate maintenance of water and wastewater infrastructures and poor solid waste management may lead to flooding, water scarcity, water pollution, adverse health effects and rehabilitation costs that may overwhelm the resilience of cities. These...
Full Text Available In Hungary detailed research work has been carried out since several years to help the process of getting prepared and adapted to the impacts of climate change. The research activities concerned mainly the health impacts of heat waves (excess mortality. Based on the results of the time series statistical analysis of weather variables and daily mortality of Budapest, it was found that a 5º C increase of the daily mean temperature increases of the risk of all cause mortality by 10%; and the risk of death due to cardio-vascular diseases by 12%. The frequency of heat waves has been increasing since the nineties. The most extreme heat wave hit the country in 2007 with an excess mortality around 1100 cases. A three level heat health warning system was launched in 2005 as an action to support adaptation. A significant association was found between global radiation and the increase of melanoma cases. The incidence of melanoma morbidity increased between 2003– 2008, the number of new cases changed from 1854 to 2610. The data of the previous years support that there is an increasing risk of vector borne diseases, as the continuous increase of the incidence of Lyme diseases (15% per year showed it. Although tick-borne encephalitis is present in the country, the incidence of the disease does not show a strong correlation with climate variability. Diseases like West Nile virus and Hanta virus infection appeared and showed an increasing tendency. The vector of Leishmaniasis also appeared in Hungary. Another consequence of climate change is the temporal and spatial change of allergenic plant species. New, invasive plants will appear, the length of pollination has been increasing.

The implementation of adaptation actions in local conservation management is a new and complex task with multiple facets, influenced by factors differing from site to site. A transdisciplinary perspective is therefore required to identify and implement effective solutions. To address this, the International Conference on Managing Protected Areas under Climate Change brought together international scientists, conservation managers, and decision-makers to discuss current experiences with local adaptation of conservation management. This paper summarizes the main issues for implementing adaptation that emerged from the conference. These include a series of conclusions and recommendations on monitoring, sensitivity assessment, current and future management practices, and legal and policy aspects. A range of spatial and temporal scales must be considered in the implementation of climate-adapted management. The adaptation process must be area-specific and consider the ecosystem and the social and economic conditions within and beyond protected area boundaries. However, a strategic overview is also needed: management at each site should be informed by conservation priorities and likely impacts of climate change at regional or even wider scales. Acting across these levels will be a long and continuous process, requiring coordination with actors outside the "traditional" conservation sector. To achieve this, a range of research, communication, and policy/legal actions is required. We identify a series of important actions that need to be taken at different scales to enable managers of protected sites to adapt successfully to a changing climate.

Health is inextricably linked to climate change. It is important for clinicians to understand this relationship in order to discuss associated health risks with their patients and to inform public policy. To provide new US-based temperature projections from downscaled climate modeling and to review recent studies on health risks related to climate change and the cobenefits of efforts to mitigate greenhouse gas emissions. We searched PubMed and Google Scholar from 2009 to 2014 for articles related to climate change and health, focused on governmental reports, predictive models, and empirical epidemiological studies. Of the more than 250 abstracts reviewed, 56 articles were selected. In addition, we analyzed climate data averaged over 13 climate models and based future projections on downscaled probability distributions of the daily maximum temperature for 2046-2065. We also compared maximum daily 8-hour average ozone with air temperature data taken from the National Oceanic and Atmospheric Administration, National Climate Data Center. By 2050, many US cities may experience more frequent extreme heat days. For example, New York and Milwaukee may have 3 times their current average number of days hotter than 32°C (90°F). High temperatures are also strongly associated with ozone exceedance days, for example, in Chicago, Illinois. The adverse health aspects related to climate change may include heat-related disorders, such as heat stress and economic consequences of reduced work capacity; respiratory disorders, including those exacerbated by air pollution and aeroallergens, such as asthma; infectious diseases, including vectorborne diseases and waterborne diseases, such as childhood gastrointestinal diseases; food insecurity, including reduced crop yields and an increase in plant diseases; and mental health disorders, such as posttraumatic stress disorder and depression, that are associated with natural disasters.

Gavage is a widely performed technique for daily dosing in laboratory rodents. Although effective, gavage comprises a sequence of potentially stressful procedures for laboratory animals that may introduce bias into experimental results, especially when the drugs to be tested interfere with stress-dependent parameters. We aimed to test vehicles suitable for drug delivery by voluntary ingestion in rats. Specifically, Male Wistar rats (age, 2 to 3 mo) were used to test nut paste (NUT), peanut butter (PB), and sugar paste (SUG) as vehicles for long-term voluntary oral administration of losartan, an angiotensin II receptor blocker. Vehicles were administered for 28 d without drug to assess effects on the glucose level and serum lipid profile. Losartan was mixed with vehicles and either offered to the rats or administered by gavage (14 d) for subsequent quantification of losartan plasma levels by HPLC. After a 2-d acclimation period, all rats voluntarily ate the vehicles, either alone or mixed with losartan. NUT administration reduced blood glucose levels. The SUG group had higher concentrations of losartan than did the gavage group, without changes in lipid and glucose profiles. Our results showed that NUT, PB, and SUG all are viable for daily single-dose voluntary ingestion of losartan and that SUG was the best alternative overall. Drug bioavailability was not reduced after voluntary ingestion, suggesting that this method is highly effective for chronic oral administration of losartan to laboratory rodents.

Study Objectives: Animal sleep deprivation (SDEP), in contrast to human SDEP, is involuntary and involves repeated exposure to aversive stimuli including the inability of the animal to control the waking stimulus. Therefore, we explored intracranial self-stimulation (ICSS), an operant behavior, as a method for voluntary SDEP in rodents. Methods: Male Sprague-Dawley rats were implanted with electroencephalography/electromyography (EEG/EMG) recording electrodes and a unilateral bipolar electrode into the lateral hypothalamus. Rats were allowed to self-stimulate, or underwent gentle handling-induced SDEP (GH-SDEP), during the first 6 h of the light phase, after which they were allowed to sleep. Other rats performed the 6 h ICSS and 1 w later were subjected to 6 h of noncontingent stimulation (NCS). During NCS the individual stimulation patterns recorded during ICSS were replayed. Results: After GH-SDEP, ICSS, or NCS, time in nonrapid eye movement (NREM) sleep and rapid eye movement (REM) sleep increased. Further, in the 24 h after SDEP, rats recovered all of the REM sleep lost during SDEP, but only 75% to 80% of the NREM sleep lost, regardless of the SDEP method. The magnitude of EEG slow wave responses occurring during NREM sleep also increased after SDEP treatments. However, NREM sleep EEG slow wave activity (SWA) responses were attenuated following ICSS, compared to GH-SDEP and NCS. Conclusions: We conclude that ICSS and NCS can be used to sleep deprive rats. Changes in rebound NREM sleep EEG SWA occurring after ICSS, NCS, and GH-SDEP suggest that nonspecific effects of the SDEP procedure differentially affect recovery sleep phenotypes.

Since the 2009 Lancet Health in South Africa Series, important changes have occurred in the country, resulting in an increase in life expectancy to 60 years. Historical injustices together with the disastrous health policies of the previous administration are being transformed. The change in leadership of the Ministry of Health has been key, but new momentum is inhibited by stasis within the health management bureaucracy. Specific policy and programme changes are evident for all four of the so-called colliding epidemics: HIV and tuberculosis; chronic illness and mental health; injury and violence; and maternal, neonatal, and child health. South Africa now has the world's largest programme of antiretroviral therapy, and some advances have been made in implementation of new tuberculosis diagnostics and treatment scale-up and integration. HIV prevention has received increased attention. Child mortality has benefited from progress in addressing HIV. However, more attention to postnatal feeding support is needed. Many risk factors for non-communicable diseases have increased substantially during the past two decades, but an ambitious government policy to address lifestyle risks such as consumption of salt and alcohol provide real potential for change. Although mortality due to injuries seems to be decreasing, high levels of interpersonal violence and accidents persist. An integrated strategic framework for prevention of injury and violence is in progress but its successful implementation will need high-level commitment, support for evidence-led prevention interventions, investment in surveillance systems and research, and improved human-resources and management capacities. A radical system of national health insurance and re-engineering of primary health care will be phased in for 14 years to enable universal, equitable, and affordable health-care coverage. Finally, national consensus has been reached about seven priorities for health research with a commitment to
It is often accepted that we may legitimately speak about voluntary euthanasia only in cases of persons who are suffering because they are incurably injured or have an incurable disease. This article argues that when we consider the moral acceptability of voluntary euthanasia, we have no good reason to concentrate only on persons who are ill or injured and suffering.

A behavior-based theory identified 2 characteristics of voluntary acts. The first, extensively explored in operant-conditioning experiments, is that voluntary responses produce the reinforcers that control them.

We examined if life-long mild caloric restriction (CR) alone or with voluntary exercise prevents the age-related changes in catecholamine biosynthetic enzyme levels in the adrenal medulla and hypothalamus. Ten-week-old Fisher-344 rats were assigned to: sedentary; sedentary+8% CR; or 8% CR+wheel running. Rats were euthanized at 6 or 24 months of age. Tyrosine hydroxylase (TH) mRNA expression was 4.4-fold higher in the adrenal medullae and 60% lower in the hypothalamus of old sedentary rats compared to young (pwheel running decreased AT(1) levels by 50% (pwheel running increased its level by 42% (pfood intake can avert age-related changes in catecholamine biosynthetic enzyme levels in the adrenal medulla and hypothalamus, possibly through affecting angiotensin II signaling.
David Lykken's proposal to license married parents for child rearing, and to deny the same opportunity to single and inept parents, springs from his deep concern for millions of youngsters cruelly subjected to abusive and neglectful rearing circumstances. Children from such inadequate homes grow up to have high rates of school failure, criminality, and drug addiction. The problem is clear, but Lykken's remedies of mandated marriage and parental licensure are unacceptable in U.S. society, where our reproductive rights are fortunately protected by our Constitution. As a devoted proponent of reproductive rights, I propose a legally and morally acceptable proposal to the same end. Increasing women's effective control of reproduction and moving toward entirely voluntary parenthood will accomplish the same goals without compromising our civil liberties.

This paper aims to identify the key challenges experienced by the families of defence force personnel following deployment. We undertook a selective review of four post-deployment challenges to the families of defence force personnel: (1) changes to relationships; (2) changes to family member roles and responsibilities; (3) adjustment of children and parenting challenges; and (4) anger, family conflict and violence. Emerging issues in the area of post-deployment adjustment are also discussed. Empirical studies of post-deployment family adjustment are lacking. Each of the reviewed challenges can contribute to psychological difficulties and precipitate contact with mental health services. The challenges faced by defence force personnel when returning from deployment arise within a family context. Clinicians should thoroughly assess these factors in families following deployment, but also recognise family strengths and resilience to these challenges. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Academic Health Centers are evolving to larger and more complex Academic Health Systems (AHS), reflecting financial stresses requiring them to become nimble, efficient, and patient (consumer) and faculty (employee) focused. The evolving AHS organization includes many positive attributes: unity of purpose, structural integration, collaboration and teamwork, alignment of goals with resource allocation, and increased financial success. The organization, leadership, and business acumen of the AHS influence directly opportunities for Departments of Medicine. Just as leadership capabilities of the AHS affect its future success, the same is true for departmental leadership. The Department of Medicine is no longer a quasi- autonomous entity, and the chairperson is no longer an independent decision-maker. Departments of Medicine will be most successful if they maintain internal unity and cohesion by not fragmenting along specialty lines. Departments with larger endowments or those with public financial support have more flexibility when investing in the academic missions. The chairpersons of the future should serve as change agents while simultaneously adopting a "servant leadership" model. Chairpersons with executive and team building skills, and business acumen and experience, are more likely to succeed in managing productive and lean departments. Quality of patient care and service delivery enhance the department's effectiveness and credibility and assure access to additional financial resources to subsidize the academic missions. Moreover, the drive for excellence, high performance and growth will fuel financial solvency. Copyright © 2016 Southern Society for Clinical Investigation. Published by Elsevier Inc.

Pacific salmon provide critical sustenance for millions of people worldwide and have far-reaching impacts on the productivity of ecosystems. Rising temperatures now threaten the persistence of these important fishes, yet it remains unknown whether populations can adapt. Here, we provide the first evidence that a Pacific salmon has both physiological and genetic capacities to increase its thermal tolerance in response to rising temperatures. In juvenile chinook salmon (Oncorhynchus tshawytscha), a 4 °C increase in developmental temperature was associated with a 2 °C increase in key measures of the thermal performance of cardiac function. Moreover, additive genetic effects significantly influenced several measures of cardiac capacity, indicative of heritable variation on which selection can act. However, a lack of both plasticity and genetic variation was found for the arrhythmic temperature of the heart, constraining this upper thermal limit to a maximum of 24.5 +/- 2.2 °C. Linking this constraint on thermal tolerance with present-day river temperatures and projected warming scenarios, we predict a 17% chance of catastrophic loss in the population by 2100 based on the average warming projection, with this chance increasing to 98% in the maximum warming scenario. Climate change mitigation is thus necessary to ensure the future viability of Pacific salmon populations.
Digitalization within the graphic arts industry is described and it is explained how it is improving and changing the print production strategies and which new kinds of print production systems are developed or can be expected. The relationship of printed media and electronic media is analyzed and a positioning for the next century is given. The state of the art of conventional printing technologies, especially using direct imagine techniques, and their position within the digital workflow are shortly described. Non-impact printing multicolor printing systems are explained, based on general design criteria and linked to existing and newly announced equipment. The use of high-tech components for building up successful systems with high reliability, high quality and low production costs is included with some examples. Digital printing systems open many opportunities in print production: distributed printing, personalization, print and book on demand are explained as examples. The overview of the several printing technologies and their positioning regarding quality and productivity leads to the scenario about the important position of printed media, also in the distant future.

Full Text Available Is there a law on environment, why hasn’t this term been precisely defined yet,why is there no harmonized meaning neither in the general, nor in the language of law. Without any doubt, our environment is composed at least from earth, water and air. It is surrounded by living organisms comprising the flora and fauna. Therefore, the definition rises from the human demands and it is in this sense that we ask a few questions. Do men create the environment of national parks? Does cities and villages with their streets and buildings represent environment? What is the case with the very distant environments? Should the term environment be restricted only to planet earth? The pollution and the soil and atmosphere degradation is dangerous for two reasons; the great speed in the case of disasters and the volume of pollution have global consequences. The field of international law on environment comprises of three main topics. Air pollution, reduction of the ozone layer and climate changes. While the politicians and economists are debating, the scientists are unanimous in how to stop the climate changes, because the warming of the planet must be stopped. The main goal of the authors of this paper is how to create educational institutions that will generate experts in order to prevent: the planet earth to remain without the climate zones till 2100; to become a planet of hot poles; the plants and animals, and even humans to became endangered and extinct, enlarging of the tropical and subtropical zones by high temperatures; the developed countries of becoming the biggest polluters and the increase of CO2 emission in the air; China and India, as new development poles, to ask for permit to pollute the earth in the same amount as the USA and Europe without a drawback for the percent of poverty. The authors seek for answers to these questions in the insufficient cooperation between the society and the higher education institutions. How can education make the

The beneficial effects of physical exercise on brain health are well documented, yet how exercise modulates cerebrovascular function is not well understood. This study used continuous arterial spin labeling magnetic resonance imaging with a hypercapnic challenge to examine changes in cerebral blood flow and vascular function after voluntary exercise in healthy, adult mice. Thirty exercise mice and twenty-one control mice were imaged prior to the start of the exercise regime (at 12 weeks of age) and after 4 weeks of voluntary exercise. After the second in vivo imaging session, we performed high-resolution ex vivo anatomical brain imaging to correlate the structural brain changes with functional measures of flow and vascular reserve. We found that exercise resulted in increases in the normocapnic and hypercapnic blood flow in the hippocampus. Moreover, the change in normocapnic blood flow between pre-exercise and post-exercise was positively correlated to the hippocampal structure volume following exercise. There was no overall effect of voluntary exercise on blood flow in the motor cortex. Surprisingly, the hypercapnic hippocampal blood flow when measured prior to the start of exercise was predictive of subsequent exercise activity. Moreover, exercise was found to normalize this pre-existing difference in hypercapnic blood flow between mice.

important events in their reproductive history with structural traits of the total population of women of same age and parity who induce abortion, the representativeness of samples was confirmed and thus generalization of results. The results indicate that a target group is clearly distinct which would decide on sterilization as a contraceptive method. Not only do more than half of the surveyed women who induce abortion believe that voluntary sterilization as a method of contraception should be available in Serbia, but also a large number of surveyed women, almost a half, would subject themselves to voluntary sterilization after having given birth to the desired number of children and when they would be convinced that sterilization does not influence health, sex potency, nor quality of sex life. Younger women, respondents with secondary education, those who gave birth to the desired number of children, as well as those who have a good relationship with their partner, and confronted themselves with a large number of induced abortions, namely those who wish to use contraception in future, are more open to voluntary sterilization. The reasons for individual non acceptance, namely undetermined standpoint towards sterilization as a contraception method, indicate that many of the registered ambivalent or negative opinions could be changed by knowledge spreading on the characteristics of voluntary sterilization.

Aim To evaluate the changes in airway responsiveness to methacholine inhalation test (MIT) when performed after an eucapnic voluntary hyperpnea challenge (EVH) in athletes. Methods Two MIT preceded (visit 1) or not (visit 2) by an EVH, were performed in 28 athletes and 24 non-athletes. Twelve athletes and 13 non-athletes had airway hyperresponsiveness (AHR) to methacholine, and 11 athletes and 11 non-athletes had AHR to EVH (EVH+). Results The MIT PC20 post-EVH was significantly lower compared to baseline MIT PC20 by 1.3±0.7 doubling-concentrations in EVH+ athletes only (pathletes and EVH+/EVH- non-athletes. A significant correlation between the change in MIT PC20 post-EVH and EVH+/EVH- status and athlete/nonathlete status was found (Adjusted R2=0.26 and pathletes and one (4%) non-athlete had a change in the diagnosis of AHR when MIT was performed consecutively to EVH. Conclusion The responsiveness to methacholine was increased by a previous indirect challenge in EVH+ athletes only. The mechanisms for such increase remain to be determined. MIT and EVH should ideally be performed on separate occasions as there is a small but possible risk to obtain a false-positive response to methacholine when performed immediately after the EVH.

Explaining the growth and change of regions and cities is one of the great challenges for social science. The field of economic geography and associated economics has developed frameworks in recent years that, while tackling major questions in spatial economic development, are deficient in their ability to explain geographical develop in a causal way, and to incorporate principal forces for change.

Grassland-based ruminant production systems are integral to sustainable food production in Europe, converting plant materials indigestible to humans into nutritious food, while providing a range of environmental and cultural benefits. Climate change poses significant challenges for such systems, their productivity and the wider benefits they supply. In this context, grassland models have an important role in predicting and understanding the impacts of climate change on grassland systems, and assessing the efficacy of potential adaptation and mitigation strategies. In order to identify the key challenges for European grassland modelling under climate change, modellers and researchers from across Europe were consulted via workshop and questionnaire. Participants identified fifteen challenges and considered the current state of modelling and priorities for future research in relation to each. A review of literature was undertaken to corroborate and enrich the information provided during the horizon scanning activities. Challenges were in four categories relating to: 1) the direct and indirect effects of climate change on the sward 2) climate change effects on grassland systems outputs 3) mediation of climate change impacts by site, system and management and 4) cross-cutting methodological issues. While research priorities differed between challenges, an underlying theme was the need for accessible, shared inventories of models, approaches and data, as a resource for stakeholders and to stimulate new research. Developing grassland models to effectively support efforts to tackle climate change impacts, while increasing productivity and enhancing ecosystem services, will require engagement with stakeholders and policy-makers, as well as modellers and experimental researchers across many disciplines. The challenges and priorities identified are intended to be a resource 1) for grassland modellers and experimental researchers, to stimulate the development of new research
The ARET (Accelerated Reduction/Elimination of Toxics) challenge began as a voluntary, non-regulatory program in 1994 to encourage a significant reduction in emissions of 117 toxic substances and the complete elimination of 30 persistent bioaccumulative and toxic substances. A total of 316 facilities from 169 companies and government organizations participate in the challenge. Each participant from eight major industrial sectors, including smelting, chemical manufacturing, oil and gas processing, manufacturing and electrical utilities, voluntarily sets emission reduction targets and reports publicly on their progress. In 1998, emissions of ARET substances were 67 per cent lower than base-year emission levels. From 1997 to 1998, participants reduced their emissions by 10 per cent. By the year 2000, the total reduction achieved by ARET participants is expected to be 75 per cent lower than base-year levels. The overall emission reduction committed by ARET participants changes as new companies join the challenge. This report included a list of the 117 ARET target substances, a directory of ARET participants, and data on emissions by each facility and by substance. 9 tabs., 23 figs., 6 appendices.

Full Text Available This paper explores the change propensity of owners of small and medium-sized enterprises (SMEs and associated challenges in the Republic of Singapore. Based on both qualitative interviews and quantitative survey research amongst Singapore's SME owners and change advocates, it identifies several critical issues with regard to the successful management of organizational transitions in small firms: "the need to change", "the mindset of small entrepreneurs", "change management know how" and "the value of external consultancy inputs". The data suggest that awareness building measures and educational efforts are necessary to enable more owners of local SMEs to benefit from change management tools and concepts as well as respective external expertise. Change management training and exposure to "best" (sectoral change management practices and successful projects facilitated by external change agents might help more small entrepreneurs to manage both intra-organizationally and externally induced organizational changes more effectively.

Faculty development for clinical faculty who assess trainees is necessary to improve assessment quality and impor tant for competency-based education. Little is known about what faculty plan to do differently after training. This study explored the changes faculty intended to make after workplace-based assessment rater training, their ability to implement change, predictors of change, and barriers encountered. In 2012, 45 outpatient internal medicine faculty preceptors (who supervised residents) from 26 institutions participated in rater training. They completed a commitment to change form listing up to five commitments and ranked (on a 1-5 scale) their motivation for and anticipated difficulty implementing each change. Three months later, participants were interviewed about their ability to implement change and barriers encountered. The authors used logistic regression to examine predictors of change. Of 191 total commitments, the most common commitments focused on what faculty would change about their own teaching (57%) and increasing direct observation (31%). Of the 183 commitments for which follow-up data were available, 39% were fully implemented, 40% were partially implemented, and 20% were not implemented. Lack of time/competing priorities was the most commonly cited barrier. Higher initial motivation (odds ratio [OR] 2.02; 95% confidence interval [CI] 1.14, 3.57) predicted change. As anticipated difficulty increased, implementation became less likely (OR 0.67; 95% CI 0.49, 0.93). While higher baseline motivation predicted change, multiple system-level barriers undermined ability to implement change. Rater-training faculty development programs should address how faculty motivation and organizational barriers interact and influence ability to change.

A climate-literate public is essential to resolving pressing problems related to global change. Future elementary teachers are a critical audience in climate and climate change education, as they will introduce children in early grades (USA grades K-8, children ages 5-14) to fundamentals of the climate system, natural and anthropogenic drivers of climate change, and impacts of global change on human and natural systems. Here we describe challenges we have encountered in teaching topics of the carbon cycle, greenhouse gases, past climate, recent anthropogenic change, and carbon footprints to future elementary teachers. We also describe how we have met (to varying degrees of success) these challenges in an introductory earth science course that is specifically designed for this audience. Two prominent challenges we have encountered are: the complex nature of the scientific content of climate change, and robust misconceptions held by our students about these topics. To address the first challenge, we attempt to adjust the scientific content to a level appropriate for future K-8 teachers, without sacrificing too much accuracy or critical detail. To address the second challenge, we explicitly discuss alternate conceptions of each topic. The use of authentic data sets can also address both of these challenges. Yet incorporating 'real' climate and paleoclimate data into the classroom poses still an additional challenge of instructional design. We use a variety of teaching approaches in our laboratory-based course including student-designed experiments, computer simulations, physical models, and authentic data sets. We have found that students strongly prefer the physical models and experiments, because these are 'hands-on' and perceived as easily adaptable to the K-8 classroom. Students often express dislike for activities that use authentic data sets (for example, an activity using graphs of CO2 and methane concentrations in Vostok ice cores), in particular because they

Voluntary wheel running in the mouse is used to assess physical performance and endurance and to model exercise training as a way to enhance health. Wheel running is a voluntary activity in contrast to other experimental exercise models in mice, which rely on aversive stimuli to force active movement. This protocol consists of allowing mice to run freely on the open surface of a slanted, plastic saucer-shaped wheel placed inside a standard mouse cage. Rotations are electronically transmitted to a USB hub so that frequency and rate of running can be captured via a software program for data storage and analysis for variable time periods. Mice are individually housed so that accurate recordings can be made for each animal. Factors such as mouse strain, gender, age, and individual motivation, which affect running activity, must be considered in the design of experiments using voluntary wheel running.

HIV testing in prison settings has been identified as an important mechanism to detect cases among high-risk, underserved populations. Several public health organizations recommend that testing across health-care settings, including prisons, be delivered in an opt-out manner. However, implementation of opt-out testing within prisons may pose challenges in delivering testing that is informed and understood to be voluntary. In a large state prison system with a policy of voluntary opt-out HIV testing, we randomly sampled adult prisoners in each of seven intake prisons within two weeks after their opportunity to be HIV tested. We surveyed prisoners' perception of HIV testing as voluntary or mandatory and used multivariable statistical models to identify factors associated with their perception. We also linked survey responses to lab records to determine if prisoners' test status (tested or not) matched their desired and perceived test status. Thirty-eight percent (359/936) perceived testing as voluntary. The perception that testing was mandatory was positively associated with age less than 25 years (adjusted relative risk [aRR]: 1.45, 95% confidence interval [CI]: 1.24, 1.71) and preference that testing be mandatory (aRR: 1.81, 95% CI: 1.41, 2.31) but negatively associated with entry into one of the intake prisons (aRR: 0.41 95% CI: 0.27, 0.63). Eighty-nine percent of prisoners wanted to be tested, 85% were tested according to their wishes, and 82% correctly understood whether or not they were tested. Most prisoners wanted to be HIV tested and were aware that they had been tested, but less than 40% understood testing to be voluntary. Prisoners' understanding of the voluntary nature of testing varied by intake prison and by a few individual-level factors. Testing procedures should ensure that opt-out testing is informed and understood to be voluntary by prisoners and other vulnerable populations.

Animal sleep deprivation (SDEP), in contrast to human SDEP, is involuntary and involves repeated exposure to aversive stimuli including the inability of the animal to control the waking stimulus. Therefore, we explored intracranial self-stimulation (ICSS), an operant behavior, as a method for voluntary SDEP in rodents. Male Sprague-Dawley rats were implanted with electroencephalography/electromyography (EEG/EMG) recording electrodes and a unilateral bipolar electrode into the lateral hypothalamus. Rats were allowed to self-stimulate, or underwent gentle handling-induced SDEP (GH-SDEP), during the first 6 h of the light phase, after which they were allowed to sleep. Other rats performed the 6 h ICSS and 1 w later were subjected to 6 h of noncontingent stimulation (NCS). During NCS the individual stimulation patterns recorded during ICSS were replayed. After GH-SDEP, ICSS, or NCS, time in nonrapid eye movement (NREM) sleep and rapid eye movement (REM) sleep increased. Further, in the 24 h after SDEP, rats recovered all of the REM sleep lost during SDEP, but only 75% to 80% of the NREM sleep lost, regardless of the SDEP method. The magnitude of EEG slow wave responses occurring during NREM sleep also increased after SDEP treatments. However, NREM sleep EEG slow wave activity (SWA) responses were attenuated following ICSS, compared to GH-SDEP and NCS. We conclude that ICSS and NCS can be used to sleep deprive rats. Changes in rebound NREM sleep EEG SWA occurring after ICSS, NCS, and GH-SDEP suggest that nonspecific effects of the SDEP procedure differentially affect recovery sleep phenotypes. © 2016 Associated Professional Sleep Societies, LLC.

Climate change has the potential to impair livestock health, with consequences for animal welfare, productivity, greenhouse gas emissions, and human livelihoods and health. Modelling has an important role in assessing the impacts of climate change on livestock systems and the efficacy of potential adaptation strategies, to support decision making for more efficient, resilient and sustainable production. However, a coherent set of challenges and research priorities for modelling livestock health and pathogens under climate change has not previously been available. To identify such challenges and priorities, researchers from across Europe were engaged in a horizon-scanning study, involving workshop and questionnaire based exercises and focussed literature reviews. Eighteen key challenges were identified and grouped into six categories based on subject-specific and capacity building requirements. Across a number of challenges, the need for inventories relating model types to different applications (e.g. the pathogen species, region, scale of focus and purpose to which they can be applied) was identified, in order to identify gaps in capability in relation to the impacts of climate change on animal health. The need for collaboration and learning across disciplines was highlighted in several challenges, e.g. to better understand and model complex ecological interactions between pathogens, vectors, wildlife hosts and livestock in the context of climate change. Collaboration between socio-economic and biophysical disciplines was seen as important for better engagement with stakeholders and for improved modelling of the costs and benefits of poor livestock health. The need for more comprehensive validation of empirical relationships, for harmonising terminology and measurements, and for building capacity for under-researched nations, systems and health problems indicated the importance of joined up approaches across nations. The challenges and priorities identified can

Realization within the US and NASA that future exploration both Human and Robotic will require innovative new technologies led to the creation of the Space Technology Mission Directorate and investment in game changing technologies with high pay-off. Some of these investments will see success and others, due to many of the constraints, will not attain their goal. The co-authors of this proposed presentation have been involved from concept to mission infusion aspects of entry technologies that are game changing. The four example technologies used to describe the challenges experienced along the pathways to success are at different levels of maturity. They are Conformal, 3-D MAT, HEEET and ADEPT. The four examples in many ways capture broad aspects of the challenges of maturation and illustrate what led some to be exceptionally successful and how others had to be altered in order remain viable game changing technologies.
Belgium legalised voluntary euthanasia in 2002, thus ending the long isolation of the Netherlands as the only country in which doctors could openly give lethal injections to patients who have requested help in dying. Meanwhile in Oregon, in the United States, doctors may prescribe drugs for terminally ill patients, who can use them to end their life--if they are able to swallow and digest them. But despite President Bush's oft-repeated statements that his philosophy is to 'trust individuals to make the right decisions' and his opposition to 'distant bureaucracies', his administration is doing its best to prevent Oregonians acting in accordance with a law that its voters have twice ratified. The situation regarding voluntary euthanasia around the world is therefore very much in flux. This essay reviews ethical arguments regarding voluntary euthanasia and physician-assisted suicide from a utilitarian perspective. I shall begin by asking why it is normally wrong to kill an innocent person, and whether these reasons apply to aiding a person who, when rational and competent, asks to be killed or given the means to commit suicide. Then I shall consider more specific utilitarian arguments for and against permitting voluntary euthanasia.

Full Text Available Besides population decline, structurally weak rural areas in Austria face a new challenge related to demographic change: the increasing heterogeneity of their aging population. From the example of the so-called ‘best agers’ - comprising people aged 55 to 65 years - this contribution makes visible patterns and consequences of growing individualized spatial behaviour and spatial perception. Furthermore, contradictions between claims, wishes and expectations and actual engagement and commitment to their residential rural municipalities are being pointed out. These empirically-based facts are rounded off by considerations on the best agers’ future migration-behaviour and the challenges for spatial planning at the municipal level.

Full Text Available Tropical reef-building coral stress levels will intensify with the predicted rising atmospheric CO2 resulting in ocean temperature and acidification increase. Most studies to date have focused on the destabilization of coral-dinoflagellate symbioses due to warming oceans, or declining calcification due to ocean acidification. In our study, pH and temperature conditions consistent with the end-of-century scenarios of the Intergovernmental Panel on Climate Change (IPCC caused major changes in photosynthesis and respiration, in addition to decreased calcification rates in the coral Acropora millepora. Population density of symbiotic dinoflagellates (Symbiodinium under high levels of ocean acidification and temperature (Representative Concentration Pathway, RCP8.5 decreased to half of that found under present day conditions, with photosynthetic and respiratory rates also being reduced by 40%. These physiological changes were accompanied by evidence for gene regulation of calcium and bicarbonate transporters along with components of the organic matrix. Metatranscriptomic RNA-Seq data analyses showed an overall down regulation of metabolic transcripts, and an increased abundance of transcripts involved in circadian clock control, controlling the damage of oxidative stress, calcium signaling/homeostasis, cytoskeletal interactions, transcription regulation, DNA repair, Wnt signaling and apoptosis/immunity/ toxins. We suggest that increased maintenance costs under ocean acidification and warming, and diversion of cellular ATP to pH homeostasis, oxidative stress response, UPR and DNA repair, along with metabolic suppression, may underpin why Acroporid species tend not to thrive under future environmental stress. Our study highlights the potential increased energy demand when the coral holobiont is exposed to high levels of ocean warming and acidification.

In summer 2010, the University of North Dakota (UND) hosted an internship for undergraduates to learn about climate change in both the classroom and group research projects. As a final project, the undergraduates were tasked to present their findings about different aspects of climate change in webcasts that would be later used in middle school classrooms in the region. Interns indicated that participation significantly improved their own confidence in future scholarly pursuits. Also, communicating about climate change, both during the project and afterwards, helped the interns feel more confident in their own learning. Use of webcasts widened the impact of student projects (e.g. YouTube dissemination), and multiple methods of student communication should continue to be an important piece of climate change education initiatives. Other key aspects of the internship were student journaling and group building. Challenges faced included media accessibility and diverse recruiting. Best practices from the UND internship will be discussed as a model for implementation at other universities. Lesson plans that complement the student-produced webcasts and adhere to regional and national standards were created during 2011. Communication between scientists and K-12 education researchers was found to be a challenge, but improved over the course of the project. These lesson plans have been reviewed both during a teacher workshop in January 2012 and by several Master teachers. Although select middle school educators have expressed enthusiasm for testing of these modules, very little hands-on testing with students has occurred. Wide-ranging roadblocks to implementation exist, including the need for adherence to state standards and texts, inadequate access to technology, and generally negative attitudes toward climate change in the region. Feedback from regional educators will be presented, and possible solutions will be discussed. Although some challenges are specific to the

There are a variety of imperatives which call us to transform engineering education. Those who have made attempts to facilitate a change in engineering education have experienced slow or no progress. The literature on change has suggestions and strategies related to educational change but most of them are not able to guide the conversations and actions effectively. People interested in understanding the challenges often ask 'what makes educational change so difficult?' This research is an effort towards finding an answer to this question. The study adopted a transdisciplinary approach while taking a systems perspective on educational change in order to examine the challenges. Instead of exploring the effectiveness of change strategies and interventions, this study sought to understand the basic nature of change in engineering education organizations. For this purpose, the study adopted an integrated theoretical framework consisting of systems thinking, complexity theory, and transformative learning theory. The methodology was designed on the complexity research paradigm with interpretive qualitative methods used for data analysis. This approach enabled understanding the social and human conditions which reduce or enhance the likelihood of change in the context of an engineering education organization. The context for this study to investigate the challenges of transformation in engineering education is efforts around educating the Engineer of 2020. Four institutional initiatives at various stages in the transformation process provided cases for investigation in the study. The engineering educators at the four institutions participating in the study had experiences of active engagement in educational change. The interpretive qualitative analysis of the participants' accounts induced a systems perspective of the challenges which faculty face in their educational transformation efforts. The inertia which educational organizations experience against change appears to

As climate change moves insect systems into uncharted territory, more knowledge about insect dynamics and the factors that drive them could enable us to better manage and conserve insect communities. Climate change may also require us revisit insect management goals and strategies and lead to a new kind of scientific engagement in management decision-making. Here we make five key points about the role of insect science in aiding and crafting management decisions, and we illustrate those points with the monarch butterfly and the Karner blue butterfly, two species undergoing considerable change and facing new management dilemmas. Insect biology has a strong history of engagement in applied problems, and as the impacts of climate change increase, a reimagined ethic of entomology in service of broader society may emerge. We hope to motivate insect biologists to contribute time and effort toward solving the challenges of climate change.

Full Text Available Ageing society, lack of skilled workforce, changes in work life careers and changes in partner and family models, a shift in societal roles of women and men, young and old, migration flows from rural to urban, multiple residences and new forms of housing and the related spatial impacts are in focus of demographic change. It is obvious that demographic change is not to be managed without gender and equality issues. Spatial planning has a crucial role in facing these challenges as spatial planning laws demand to ensure equal access to housing, services and labour markets and to organize transparent and inclusive decision making procedures. The paper explores key concepts, methods and selected case studies from Europe on gender planning trying to focus on the potential for innovating planning discipline and tackling with demographic change issues in rural areas. Cases from Bavaria and Austria compared to rural regions in Eastern Germany with high female emigration show concrete planning approaches.
Full Text Available The risks and opportunities presented by climate change for Small and Medium Sized Enterprises (SMEs have been largely overlooked by previous research. The subsequent lack of knowledge in this field makes it difficult for SMEs to engage with climate change in a meaningful, profitable, and sustainable way. Further, current research cannot explain why SMEs rarely engage with climate change. We examine critically 30 SMEs, which engage with climate change knowledges and 5 Innovation-Support-Organizations (ISOs that communicate climate change knowledges. Over a three-year period we explore why and how these businesses approach the knowledge gap between climate change science and business practice, drawing on a variety of ethnographic research methods: (1 in-depth semi-structured and open interviews; (2 participant observations; and (3 practitioners’ workshops. The results demonstrate that business’ mitigation and adaptation strategies are lay-knowledge-dependent, derived from personal values, space, and place identity. To enhance the number of SMEs engaging with climate change, maximize the potential value of climate change for the econo- my and establish a low carbon economy, climate change communication needs to target personal values of business leaders. The message should highlight local impacts of climate change, the benefits of engagement to (the local society and economy, and possible financial benefits for the business. Climate change communication therefore needs to go beyond thinking about potential financial benefits and scientific evidence and challenge values, cultures, and beliefs to stimulate economic, political, and social frameworks that promote values-based decision-making.

Most action to address contemporary complex challenges, including the urgent issues of global sustainability, occurs piecemeal and without meaningful guidance from leading complex change knowledge and methods. The potential benefit of using such knowledge is greater efficacy of effort and investment. However, this knowledge and its associated tools and methods are under-utilized because understanding about them is low, fragmented between diverse knowledge traditions, and often requires shifts in mindsets and skills from expert-led to participant-based action. We have been engaged in diverse action-oriented research efforts in Large System Change for sustainability. For us, "large" systems can be characterized as large-scale systems - up to global - with many components, of many kinds (physical, biological, institutional, cultural/conceptual), operating at multiple levels, driven by multiple forces, and presenting major challenges for people involved. We see change of such systems as complex challenges, in contrast with simple or complicated problems, or chaotic situations. In other words, issues and sub-systems have unclear boundaries, interact with each other, and are often contradictory; dynamics are non-linear; issues are not "controllable", and "solutions" are "emergent" and often paradoxical. Since choices are opportunity-, power- and value-driven, these social, institutional and cultural factors need to be made explicit in any actionable theory of change. Our emerging network is sharing and building a knowledge base of experience, heuristics, and theories of change from multiple disciplines and practice domains. We will present our views on focal issues for the development of the field of large system change, which include processes of goal-setting and alignment; leverage of systemic transitions and transformation; and the role of choice in influencing critical change processes, when only some sub-systems or levels of the system behave in purposeful ways

Furthermore, the state needs the voluntary system to exist as well in order to strengthen its position. Therefore, the voluntary and the compulsory systems collaborate to attract global initiatives,which is contributing to the high complex of meta governance.

The need for organizational innovation as a means of improving health-care quality and containing costs is widely recognized, but while a growing body of research has improved knowledge of implementation, very little has considered the challenges involved in sustaining change - especially organizational change led 'bottom-up' by frontline clinicians. This study addresses this lacuna, taking a longitudinal, qualitative case-study approach to understanding the paths to sustainability of four organizational innovations. It highlights the importance of the interaction between organizational context, nature of the innovation and strategies deployed in achieving sustainability. It discusses how positional influence of service leads, complexity of innovation, networks of support, embedding in existing systems, and proactive responses to changing circumstances can interact to sustain change. In the absence of cast-iron evidence of effectiveness, wider notions of value may be successfully invoked to sustain innovation. Sustainability requires continuing effort through time, rather than representing a final state to be achieved. Our study offers new insights into the process of sustainability of organizational change, and elucidates the complement of strategies needed to make bottom-up change last in challenging contexts replete with competing priorities.

I discuss some challenges state initiatives of this type may encounter considering the existence of local contentious political issues among various actors – fishers and the state-owned oil industry – that are at the core of the emergence of coastal environmental changes in the study site. A close analysis of local political, economic and environmental processes in coastal lagoon communities illustrates the existence of contentious issues among powerful actors over territory and its resources. It is in the context of these local, on the ground, issues that I argue that climate change adaptation interventions become highly political. I also argue that climate change policy analysis must be done in light of past and failed state interventions in Tabasco that have had a negative impact on ecosystems and fishers’ livelihoods. My analysis of climate change adaptation initiatives and fishers’ views on their local environmental problems is based on political ecology approaches to environmental narratives and critical literature on climate change.

Full Text Available The publishing industry is at a turning point. Facing the first major disruptive innovation in five centuries, its long-established structure and business model are at stake. Building on literature based on the pitfalls for incumbents, we interviewed key executives from the major publishers in Brazil to understand their perspective. We find that not only are they facing those pitfalls, but we also propose a new one, The Industry View Trap, concerning challenges created by convergence, the difficulty to deal with changes in the ecosystem and the fact that the very definition of the industry you're part of might have changed.
Full Text Available The current changes in global climatic regimes present a significant societal challenge, affecting in all likelihood insect physiology, biochemistry, biogeography and population dynamics. With the increasing resistance of many insect pest species to chemical insecticides and an increasing organic food market, pest control strategies are slowly shifting towards more sustainable, ecologically sound and economically viable options. Biologically based pest management strategies present such opportunities through predation or parasitism of pests and plant direct or indirect defense mechanisms that can all be important components of sustainable integrated pest management programs. Inevitably, the efficacy of biological control systems is highly dependent on natural enemy-prey interactions, which will likely be modified by changing climates. Therefore, knowledge of how insect pests and their natural enemies respond to climate variation is of fundamental importance in understanding biological insect pest management under global climate change. Here, we discuss biological control, its challenges under climate change scenarios and how increased global temperatures will require adaptive management strategies to cope with changing status of insects and their natural enemies.
This presentation provides an overview of international voluntary renewable energy markets, with a focus on the United States and Europe. The voluntary renewable energy market is the market in which consumers and institutions purchase renewable energy to match their electricity needs on a voluntary basis. In 2010, the U.S. voluntary market was estimated at 35 terawatt-hours (TWh) compared to 300 TWh in the European market, though key differences exist. On a customer basis, Australia has historically had the largest number of customers, pricing for voluntary certificates remains low, at less than $1 megawatt-hour, though prices depend on technology.
Full Text Available Climate change is one of the main environmental issues challenging cities in the 21th century. At present, more than half of the world population lives in cities and the latter are responsible for 60% to 80% of global energy consumption and greenhouse gas (GHG emissions, which are the main causes of the change in climate conditions. In the meantime, they are seriously threatened by the heterogeneous climate-related phenomena, very often exacerbated by the features of the cities themselves. In the last decade, international and European efforts have been mainly focused on mitigation rather than on adaptation strategies. Europe is one of the world leaders in global mitigation policies, while the issue of adaptation has gained growing importance in the last years. As underlined by the EU Strategy on adaptation to climate change, even though climate change mitigation still remains a priority for the global community, large room has to be devoted to adaptation measures, in order to effectively face the unavoidable impacts and related economic, environmental and social costs of climate change (EC, 2013. Thus, measures for adaptation to climate change are receiving an increasing financial support and a growing number of European countries are implementing national and urban adaptation strategies to deal with the actual and potential climate change impacts. According to the above considerations, this paper explores strengths and weaknesses of current adaptation strategies in European cities. First the main suggestions of the European Community to improve urban adaptation to climate change are examined; then, some recent Adaptation Plans are analyzed, in order to highlight challenges and opportunities arising from the adaptation processes at urban level and to explore the potential of Adaptation Plans to promote a smart growth in the European cities.

Climate change mitigation in developing economies is a balancing act, between economic development and environmental sustainability. The need for market friendly determinants for low carbon economy, without compromising economic development is of essence. The aim of the study is to determine market friendly factors, which motivates voluntary carbon information disclosure, in the real estate industry. The study modeled economic factor with three variables and financial market factor with three variables against voluntary carbon information disclosure in the real estate industry. Structural equation modeling was used for the modeling and content analysis was used to collect data on the level of voluntary carbon information disclosure, from 2013 annual reports of 126 real estate sector companies listed in the Kuala Lumpur Stock Exchange (KLSE). The model achieved a good fit, and was acceptable prediction. The results show that financial market factor has a significant predictive influence on voluntary carbon disclosure. The application of the result is that financial market factor is has a significantly positive influence on companies’ willingness to make voluntary carbon disclosure in the real estate industry. The result may be limited to the real estate industry that is highly leveraged on syndicated fund.

In the context of consent, "voluntariness" refers to a patient's right to make health care choices free of any undue influence. However, a patient's freedom to make choices can be compromised by internal factors such as pain and by external factors such as force, coercion and manipulation. In exceptional circumstances--for example, involuntary admission to hospital--patients may be denied their freedom of choice; in such circumstances the least restrictive means possible of managing the patie...

The growing demand for integrative (interdisciplinary or transdisciplinary) approaches in the field of environmental and landscape change has increased the number of PhD students working in this area. Yet, the motivations to join integrative projects and the challenges for PhD students have so far not been investigated. The aims of this paper were to identify the understanding of PhD students with regard to integrative research, their motivations to join integrative projects, their expectations in terms of integration and results, and to reveal the challenges they face in integrative projects. We collected data by a questionnaire survey of 104 PhD students attending five PhD Master Classes held from 2003 to 2006. We used manual content analysis to analyse the free-text answers. The results revealed that students lack a differentiated understanding of integrative approaches. The main motivations to join integrative projects were the dissertation subject, the practical relevance of the project, the intellectual stimulation of working with different disciplines, and the belief that integrative research is more innovative. Expectations in terms of integration were high. Core challenges for integration included intellectual and external challenges such as lack of knowledge of other disciplines, knowledge transfer, reaching depth, supervision, lack of exchange with other students and time demands. To improve the situation for PhD students, we suggest improving knowledge on integrative approaches, balancing practical applicability with theoretical advancement, providing formal introductions to other fields of research, and enhancing institutional support for integrative PhD projects.

Si has been considered as a promising alternative anode for next-generation Li-ion batteries (LIBs) because of its high theoretical energy density, relatively low working potential, and abundance in nature. However, Si anodes exhibit rapid capacity decay and an increase in the internal resistance, which are caused by the large volume changes upon Li insertion and extraction. This unfortunately limits their practical applications. Therefore, managing the total volume change remains a critical challenge for effectively alleviating the mechanical fractures and instability of solid-electrolyte-interphase products. In this regard, we review the recent progress in volume-change-accommodating Si electrodes and investigate their ingenious structures with significant improvements in the battery performance, including size-controlled materials, patterned thin films, porous structures, shape-preserving shell designs, and graphene composites. These representative approaches potentially overcome the large morphologic changes in the volume of Si anodes by securing the strain relaxation and structural integrity in the entire electrode. Finally, we propose perspectives and future challenges to realize the practical application of Si anodes in LIB systems.

The size of the long-latency component of the stretch reflex has been examined in the time interval between a signal to move and the required rapid voluntary contraction of triceps and flexor pollicis longus in 8 normal subjects. Bilateral movements of the elbow and thumb were made following an auditory signal. In 50% of the trials a torque pulse was applied unilaterally in order to elicit a stretch reflex response in one arm. The voluntary response in the contralateral arm was uncorrupted by a stretch reflex response, so was used as an indicator of voluntary reaction time. Control experiments, using an electrical stimulus to the fingers rather than muscle stretch, verified that both arms reacted almost simultaneously to the auditory cue, even when the reaction time was shortened by the presence of a unilateral electrical stimulus. Similarly, an interposed muscle stretch stimulus considerably reduced the reaction time to the audio signal. Because of this, the start of the voluntary EMG response frequently 'over-lapped' the end of the long-latency stretch reflex. Failure to take this shortening of voluntary reaction time into consideration can lead to the erroneous conclusion that reflex gain is increased prior to a rapid movement. If the 'overlap' of EMG responses is accounted for, very little change in the size of the long-latency stretch reflex is evident prior to activation of the muscles responsible for the movement of either the elbow or the thumb.

Changing labour markets, increased calls for selection and excellence, and increased diversity and individualisation have repercussions on how educational systems can prepare youth for work, optimise knowledge production, achieve equality of opportunity, and socialise students into active civic engagement. This paper discusses four central tasks of schooling and examines to what extent societal developments challenge education policy to deliver on the tasks at hand. Particular attention is given to the challenges Europe's strongly diversified educational systems are currently facing. Both the Netherlands and Germany, for example, have been offering vocationally-oriented pathways alongside traditional academic higher education for some time. But today's ongoing changes in job descriptions, mainly due to ever-accelerating technological developments, are causing a risk of skills obsolescence which can only be avoided by continuous upskilling and/or reskilling of a sufficiently flexible workforce. Overcoming differences of intelligence as well as differences of diverse socioeconomic, ethnic and linguistic backgrounds by way of education is another challenge, as is fostering "soft" skills and political awareness. This paper investigates the effectiveness of current education systems in preparing citizens for a functioning modern society.

The impact of climate change on Megacities as well as feedback mechanisms from urban conglomerations to climate change are issues which will have major consequences to the urban life quality. One of such issues is the impact of climate change on air quality in Megacities and its future development as well as the contribution of green house gases (GHG) from urban emissions to climate change. Based on a survey of more than 500 stakeholders from 25 cites it was expressed, that air pollution is the most significant environmental challenge followed by traffic congestion issues. This statement enforces the scientific work on air quality in which vehicular emissions play a major role for the air pollution in urban conglomerations and further - interdisciplinary - investigations on air pollution have to be done. In view of the ongoing climate change - which will amplify environmental problems - it is important that the scientific community of climate change, air pollution, health and social science experts convene with regional and local stakeholders in order to introduce suitable measures and to reduce and minimize air pollution levels and health impacts. Results of the assessment of the air quality, the impact of global climate change and its consequences on human health in large urban agglomerations will be discussed and presented.

Land-use and land-cover change (LULCC) represents one of the key drivers of global environmental change. However, the processes and drivers of anthropogenic land-use activity are still overly simplistically implemented in terrestrial biosphere models (TBMs). The published results of these models are used in major assessments of processes and impacts of global environmental change, such as the reports of the Intergovernmental Panel on Climate Change (IPCC). Fully coupled models of climate, land use and biogeochemical cycles to explore land use-climate interactions across spatial scales are currently not available. Instead, information on land use is provided as exogenous data from the land-use change modules of integrated assessment models (IAMs) to TBMs. In this article, we discuss, based on literature review and illustrative analysis of empirical and modeled LULCC data, three major challenges of this current LULCC representation and their implications for land use-climate interaction studies: (I) provision of consistent, harmonized, land-use time series spanning from historical reconstructions to future projections while accounting for uncertainties associated with different land-use modeling approaches, (II) accounting for sub-grid processes and bidirectional changes (gross changes) across spatial scales, and (III) the allocation strategy of independent land-use data at the grid cell level in TBMs. We discuss the factors that hamper the development of improved land-use representation, which sufficiently accounts for uncertainties in the land-use modeling process. We propose that LULCC data-provider and user communities should engage in the joint development and evaluation of enhanced LULCC time series, which account for the diversity of LULCC modeling and increasingly include empirically based information about sub-grid processes and land-use transition trajectories, to improve the representation of land use in TBMs. Moreover, we suggest concentrating on the

Since the beginnings of government-sponsored fire research in the United States in the early 1900s, fire research has had close ties with fire management. However, as the social, economic, and environmental impacts of wildland fires and their management are increasingly recognized by the broader land management and environmental policy communities and by Congress, the roles, funding, and potential impacts of fire-related research are changing rapidly. Fire research is increasingly interdisciplinary and multiscalar. It is increasingly addressing a broader range of issues that require new competencies, new collaborations, new tools, and a strong vision of future needs. Fire is a dominant disturbance process in many terrestrial ecosystems, and its wise management is critical to society, to ecosystem health, and to resource sustainability. The challenges to fire research are great, the issues are complex. Developing research programs to meet these challenges is critical to ensuring protection of life and property, while meeting resource needs and maintaining a healthy environment.

Risk assessment (RA) of manufactured nanomaterials (MNM) is essential for regulatory purposes and risk management activities. Similar to RA of "classical" chemicals, MNM RA requires knowledge about exposure as well as of hazard potential and dose response relationships. What makes MNM RA especially challenging is the multitude of materials (which is expected to increase substantially in the future), the complexity of MNM value chains and life cycles, the accompanying possible changes in material properties over time and in contact with various environmental and organismal milieus, and the difficulties to obtain proper exposure data and to consider the proper dose metric. This article discusses these challenges and also critically overviews the current state of the art regarding MNM RA approaches. Copyright © 2016 Elsevier Inc. All rights reserved.
Full Text Available Although Alzheimer's disease (AD primarily manifests as cognitive deficits, the implicit sensorimotor processes that underlie social interactions, such as automatic imitation, seem to be preserved in mild and moderate stages of the disease, as is the ability to communicate with other persons. Nevertheless, when AD patients face more challenging tasks, which do not rely on automatic processes but on explicit voluntary mechanisms and require the patient to pay attention to external events, the cognitive deficits resulting from the disease might negatively affect patients’ behaviour. The aim of the present study was to investigate whether voluntary motor imitation, i.e. a volitional mechanism that involves observing another person’s action and translating this perception into one’s own action, was affected in patients with Alzheimer’s disease. Further, we tested whether this ability was modulated by the nature of the observed stimulus by comparing the ability to reproduce the kinematic features of a human demonstrator with that of a computerized-stimulus. AD patients showed an intact ability to reproduce the velocity of the observed movements, particularly when the stimulus was a human agent. This result suggests that high-level cognitive processes involved in voluntary imitation might be preserved in mild and moderate stages of AD and that voluntary imitation abilities might benefit from the implicit interpersonal communication established between the patient and the human demonstrator.

Full Text Available Over the past 20 years there have been many changes to the primary and secondary educational system that have impacted students, teachers, and post-secondary institutions across the United States of America. One of the most important is the large number of standardized tests students are required to take to show adequate performance in school. Students think differently because they are taught differently due to this focus on standardized testing, thus changing the skill sets students acquire in secondary school. This presents a critical problem for colleges and universities, as they now are using practices for and have expectations of these students that are unrealistic for the changing times. High dropout rates in the colleges of engineering have been attributed to the cultural atmosphere of the institution. Students have reported a low sense of belonging and low relatability to course material. To reduce negative experiences and increase motivation, Challenge Based Learning (CBL was introduced in an undergraduate Basic Electric Circuits (BEC course. CBL is a structured model for course content with a foundation in problem-based learning. CBL offers general concepts from which students derive the challenges they will address. Results show an improved classroom experience for students who were taught with CBL.

The Chronic Care Model (CCM) provides a conceptual framework for transforming health care for patients with chronic conditions; however, little is known about how to best design and implement its specifics. One large health care organization that tried to implement the CCM in primary care provided an opportunity to study these issues. We conducted a qualitative, comparative case study of 5 of 18 group clinics 18 to 23 months after the implementation began. Built on knowledge of the clinics from a previous study of advanced access implementation, data included in-depth interviews with organizational leaders and varied clinic personnel, observation of clinic care processes, and review of written materials. Relatively small and highly variable care process changes were made during the study period. The change process underwent several marked shifts in strategy when initial efforts failed to achieve much and bore little resemblance to the change process used in the previously successful large-scale implementation of advanced access scheduling. Many barriers were identified, including too many competing priorities, a lack of specificity and agreement about the care process changes desired, and little engagement of physicians. These findings highlight specific organizational challenges with health care transformation in the absence of a blueprint more specific than the CCM. Effective models of organizational change and detailed examples of proven, feasible care changes still need to be demonstrated if we are to transform care as called for by the Institute of Medicine.

Half of Earth’s land surface has been altered by human activities, creating various consequences on the climate and weather systems at local to global scales, which in turn affect a myriad of land surface processes and the adaptation behaviors. This study reviews the status and major knowledge gaps in the interactions of land and atmospheric changes and present 11 grand challenge areas for the scientific research and adaptation community in the coming decade. These land-cover and land-use change (LCLUC)-related areas include 1) impacts on weather and climate, 2) carbon and other biogeochemical cycles, 3) biospheric emissions, 4) the water cycle, 5) agriculture, 6) urbanization, 7) acclimation of biogeochemical processes to climate change, 8) plant migration, 9) land-use projections, 10) model and data uncertainties, and, finally, 11) adaptation strategies. Numerous studies have demonstrated the effects of LCLUC on local to global climate and weather systems, but these putative effects vary greatly in magnitude and even sign across space, time, and scale and thus remain highly uncertain. At the same time, many challenges exist toward improved understanding of the consequences of atmospheric and climate change on land process dynamics and services. Future effort must improve the understanding of the scale-dependent, multifaceted perturbations and feedbacks between land and climate changes in both reality and models. To this end, one critical cross-disciplinary need is to systematically quantify and better understand measurement and model uncertainties. Finally, LCLUC mitigation and adaptation assessments must be strengthened to identify implementation barriers, evaluate and prioritize opportunities, and examine how decision-making processes work in specific contexts.

The need to integrate economic and epidemiological aspects in the clinical perspective leads to a proposal for the analysis of health disparities and to an evaluation of the health services and of the new challenges which are now being faced by health system reforms in middle income countries. To identify the epidemiological changes, the demand for health services and economic burden from chronic diseases (diabetes and hypertension) in a middle income county. We conducted longitudinal analyses of costs and epidemiological changes for diabetes and hypertension in the Mexican health system. The study population included both the insured and uninsured populations. The cost-evaluation method was used, based on the instrumentation and consensus techniques. To estimate the epidemiological changes and financial consequences for 2014-2016, six models were constructed according to the Box-Jenkins technique, using confidence intervals of 95%, and the Box-Pierce test. Regarding epidemiological changes expected in both diseases for 2014 vs. 2016, an increase is expected, although results predict a greater increase for diabetes, 8-12% in all three studied institutions, (p management per patient in the case of diabetes, and from $485 to $622 in patients with hypertension. Comparing financial consequences of health services required by insured and uninsured populations, the greater increase (23%) will be for the insured population (p financial requirements of both diseases will amount to 19.5% of the total budget for the uninsured and 12.5% for the insured population. If the risk factors and the different health care models remain as they currently are, the economic impact of expected epidemiological changes on the social security system will be particularly strong. Another relevant challenge is the appearance of internal competition in the use and allocation of financial resources with programs for other chronic and infectious diseases.
Full Text Available The examination of the relationship between communication and development in a context of climate change and global systemic crisis challenges us to come to terms with the importance of the limits of human intervention on nature and against the logic of unlimited growth determined by modern and capitalist rationality. In this context, Latin America has usually played an influential and pioneering role in the questioning of development imaginaries from the dependency and participatory theories in the 60s and 70s and nowadays through the biocentric turn proposed by Living Well and other critical ecology perspectives.

This is the second of two articles on challenges to future food security in the Asia Pacific region. It focuses on five mechanisms, which can be conceptualised as pathways by which pessimistic Malthusian scenarios, described in the first paper, may become manifest. The mechanisms are (1) climate change, (2) water scarcity, (3) tropospheric ozone pollution, (4) impending scarcity of phosphorus and conventional oil and (5) the possible interaction between future population displacement, conflict and poor governance. This article concludes that a sustainable improvement in food security requires a radical transformation in society's approach to the environment, population growth, agricultural research and the distribution of rights, opportunities and entitlements.

This article examines the restriction of smoking on university campuses in the Canadian context. Indoor smoking on campus is now completely prohibited by law, and universities are increasingly moving to restrict, or prohibit, outdoor smoking on their grounds. The research focuses on three case studies to identify changes in spatial restrictions on campus smoking over the last four decades (1970-2010), and to determine the challenges involved in establishing bans in outdoor areas of campus. The three universities were selected for their different approaches to the issue of outdoor smoking. Data collection involved semi-structured interviews with 36 key informants, conducted from September 2010 to January 2011, supplemented by documentary information. Interview data were analysed thematically. Protection against environmental tobacco smoke (ETS) on campus proceeded incrementally, via policy-making at the provincial, municipal and institutional levels. Historically, institutional bans on indoor smoking were particularly significant, but their health benefits could be limited by the presence of private property on campus. Universities continue to initiate smoking restrictions today, with respect to outdoor bans. However, respondents reported myriad challenges in developing, implementing and maintaining such bans. Five principal concerns were articulated: the need for ongoing policy communication; management of community relations as smokers are displaced from campus; enforcement to ensure that the policy has practical effect; safety concerns; and difficulties relating to campus layout. Because challenges are diverse and contextual, effective protection against outdoor ETS on campus is likely to require an ongoing commitment on the part of administrators. © 2012 Blackwell Publishing Ltd.

One way that climate change will impact animal distributions is by altering habitat suitability and habitat fragmentation. Understanding the impacts of climate change on currently threatened species is of immediate importance because complex conservation planning will be required. Here, we mapped changes to the distribution, suitability, and fragmentation of giant panda habitat under climate change and quantified the direction and elevation of habitat shift and fragmentation patterns. These data were used to develop a series of new conservation strategies for the giant panda. Qinling Mountains, Shaanxi, China. Data from the most recent giant panda census, habitat factors, anthropogenic disturbance, climate variables, and climate predictions for the year 2050 (averaged across four general circulation models) were used to project giant panda habitat in Maxent. Differences in habitat patches were compared between now and 2050. While climate change will cause a 9.1% increase in suitable habitat and 9% reduction in subsuitable habitat by 2050, no significant net variation in the proportion of suitable and subsuitable habitat was found. However, a distinct climate change-induced habitat shift of 11 km eastward by 2050 is predicted firstly. Climate change will reduce the fragmentation of suitable habitat at high elevations and exacerbate the fragmentation of subsuitable habitat below 1,900 m above sea level. Reduced fragmentation at higher elevations and worsening fragmentation at lower elevations have the potential to cause overcrowding of giant pandas at higher altitudes, further exacerbating habitat shortage in the central Qinling Mountains. The habitat shift to the east due to climate change may provide new areas for giant pandas but poses severe challenges for future conservation.

Full Text Available This article aims to examine the impact of climate change on food security in South Africa. For this purpose, the article adopted a desktop study approach. Previous studies, reports, surveys and policies on climate change and food (insecurity. From this paper’s analysis, climate change presents a high risk to food security in sub-Saharan countries from crop production to food distribution and consumption. In light of this, it is found that climate change, particularly global warming, affects food security through food availability, accessibility, utilisation and affordability. To mitigate these risks, there is a need for an integrated policy approach to protect the arable land against global warming. The argument advanced in this article is that South Africa’s ability to adapt and protect its food items depends on the understanding of risks and the vulnerability of various food items to climate change. However, this poses a challenge in developing countries, including South Africa, because such countries have weak institutions and limited access to technology. Another concern is a wide gap between the cost of adapting and the necessary financial support from the government. There is also a need to invest in technologies that will resist risks on food systems.

The last three decades of surveillance data shows a drastic increase of cholera prevalence in the largest cholera-endemic city of the world - Dhaka, Bangladesh. Emerging megacities in the developing world, especially those located in coastal regions of the tropics remain vulnerable to similar. However, there has not been any systematic study on linking the long-term disease trends with changes in related climatic, environmental, or societal variables. Here, we analyze the 30-year dynamics of urban cholera prevalence in Dhaka with changes in climatic or societal factors: regional hydrology, flooding, water usage, changes in distribution systems, population growth and density in urban settlements, as well as shifting climate patterns. An interesting change is observed in the seasonal trends of cholera incidence; while an endemic upward trend is seen in the dry season, the post-monsoon trend seem to be more epidemic in nature. Evidence points to growing urbanization and rising population in unplanned settlements that have negligible to poor water and sanitation systems compounded by increasing frequency of record flood events. Growing water scarcity in the dry season and lack of sustainable water and sanitation infrastructure for urban settlements have increased endemicity of spring outbreaks, while record flood events and prolonged post-monsoon inundation have contributed to increased epidemic outbreaks in fall. We analyze our findings with the World Health Organization recommended guidelines and investigate water sustainability challenges in the context of climatic and anthropogenic changes in the region.
It is widely agreed that the concentration of greenhouse gases in the earth`s atmosphere is increasing, that this increase is a consequence of man`s activities, and that there is significant risk that this will lead to changes in the earth`s climate. The question is now being discussed what, if anything, we should be doing to minimize and/or adapt to changes in climate. Virtually every statement on this matter; from the US Office of Technology Assessment, to the National Academy of Science, to the Nairobi Declaration on Climatic Change, includes some recommendation for planting and protecting forests. In fact, forestry is intimately involved in the climate change debate for several reasons: changing climate patterns will affect existing forests, tropical deforestation is one of the major sources of greenhouse gases to the atmosphere, reforestation projects could remove additional carbon dioxide from the atmosphere and there is renewed interest in wood-based or other renewable fuels to replace fossil fuels. Part of the enthusiasm for forestry-related strategies in a greenhouse context is the perception that forests not only provide greenhouse benefits but also serve other desirable social objectives. This discussion will explore the current range of thinking in this area and try to stimulate additional thinking on the rationality of the forestry-based approaches and the challenges posed for US forestry.

Energy systems are significantly vulnerable to current climate variability and extreme events. As climate change becomes more pronounced, the risks and vulnerabilities will be exacerbated. To date, energy sector adaptation issues have received very limited attention. In this paper, a climate risk...... management framework is used as the basis for identifying key challenges and opportunities to enhance the integration of climate change adaptation in energy planning and decision-making. Given its importance for raising awareness and for stimulating action by planners and decision-makers, emphasis is placed...... barriers to integration of climate risks and adaptive responses in energy planning and decision making. Both detailed assessments of the costs and benefits of integrating adaptation measures and rougher ‘order of magnitude’ estimates would enhance awareness raising and momentum for action....

Our goal is to design a prediction and decision system for real-time use during a professional car race. In designing a knowledge discovery process for racing, we faced several challenges that were overcome only when domain knowledge of racing was carefully infused within statistical modeling techniques. In this article, we describe how we leveraged expert knowledge of the domain to produce a real-time decision system for tire changes within a race. Our forecasts have the potential to impact how racing teams can optimize strategy by making tire-change decisions to benefit their rank position. Our work significantly expands previous research on sports analytics, as it is the only work on analytical methods for within-race prediction and decision making for professional car racing.

The desire to use sentinel species as early warning indicators of impending climate change effects on entire ecosystems is attractive, but we need to verify that such approaches have sound biological foundations. A recent large-scale warming event in the North Pacific Ocean of unprecedented magnitude and duration allowed us to evaluate the sentinel status of giant kelp, a coastal foundation species that thrives in cold, nutrient-rich waters and is considered sensitive to warming. Here, we show that giant kelp and the majority of species that associate with it did not presage ecosystem effects of extreme warming off southern California despite giant kelp's expected vulnerability. Our results challenge the general perception that kelp-dominated systems are highly vulnerable to extreme warming events and expose the more general risk of relying on supposed sentinel species that are assumed to be very sensitive to climate change.

Urban drainage systems are in general failing in their functions mainly due to non-stationary climate and rapid urbanization. As these systems are becoming less efficient, issues such as sewer overflows and increase in urban flooding leading to surge in pollutant loads to receiving water bodies are becoming pervasive rapidly. A comprehensive investigation is required to understand these factors impacting the functioning of urban drainage, which vary spatially and temporally and are more complex when weaving together. It is necessary to establish a cost-effective, integrated planning and design framework for every local area by incorporating fit for purpose alternatives. Carefully selected adaptive measures are required for the provision of sustainable drainage systems to meet combined challenges of climate change and urbanization. This paper reviews challenges associated with urban drainage systems and explores limitations and potentials of different adaptation alternatives. It is hoped that the paper would provide drainage engineers, water planners, and decision makers with the state of the art information and technologies regarding adaptation options to increase drainage systems efficiency under changing climate and urbanization.
Full Text Available Shale gas proponents argue this unconventional fossil fuel offers a “bridge” towards a cleaner energy system by offsetting higher-carbon fuels such as coal. The technical feasibility of reconciling shale gas development with climate action remains contested. However, we here argue that governance challenges are both more pressing and more profound. Reconciling shale gas and climate action requires institutions capable of responding effectively to uncertainty; intervening to mandate emissions reductions and internalize costs to industry; and managing the energy system strategically towards a lower carbon future. Such policy measures prove challenging, particularly in jurisdictions that stand to benefit economically from unconventional fuels. We illustrate this dilemma through a case study of shale gas development in British Columbia, Canada, a global leader on climate policy that is nonetheless struggling to manage gas development for mitigation. The BC case is indicative of the constraints jurisdictions face both to reconcile gas development and climate action, and to manage the industry adequately to achieve social licence and minimize resistance. More broadly, the case attests to the magnitude of change required to transform our energy systems to mitigate climate change.

Recruitment of highly qualified science and mathematics graduates has become a widespread strategy to enhance the quality of education in the field of STEM. However, attrition rates are very high suggesting preservice education programs are not preparing them well for the career change. We analyse the experiences of professionals who are scientists and have decided to change careers to become teachers. The study followed a group of professionals who undertook a 1-year preservice teacher education course and were employed by secondary schools on graduation. We examined these teachers' experiences through the lens of self-determination theory, which posits autonomy, confidence and relatedness are important in achieving job satisfaction. The findings indicated that the successful teachers were able to achieve a sense of autonomy and confidence and, in particular, had established strong relationships with colleagues. However, the unique challenges facing career-change professionals were often overlooked by administrators and colleagues. Opportunities to build a sense of relatedness in their new profession were often absent. The failure to establish supportive relationships was decisive in some teachers leaving the profession. The findings have implications for both preservice and professional in-service programs and the role that administrators play in supporting career-change teachers.

Extremes weather changes surpassing their usual statistical ranges and tumbling records in India could be an early warning bell of global warming. Extreme weather events like the recent record setting in western Indian city of Mumbai or all time high fatalities due to the heat wave in southern Indian states or increasing vulnerability of easten Indian states to flood could all be a manifestation of climate change in the Asian subcontinent. While the skeptics may be inclined to dismiss these events as simple local aberrations, when viewed in an epidemiological paradigm in terms of person, time and space couple with frequency, intensity and fatalities, it could well be an early manifestation of climate change. Global warming poses serious challenge to the health sector and hence warrants emergency health preparedness and response. Climate-sensitive diseases are among the largest global killers, hence major brunt of global climate change in terms of adverse health impact will be mostly borne by poor and developing countries in Asia, given the levels of poverty, nutional levels and poor public health infrastructure.

In alpine regions worldwide, climate change is dramatically altering ecosystems and affecting biodiversity in many ways. For streams, receding alpine glaciers and snowfields, paired with altered precipitation regimes, are driving shifts in hydrology, species distributions, basal resources, and threatening the very existence of some habitats and biota. Alpine streams harbour substantial species and genetic diversity due to significant habitat insularity and environmental heterogeneity. Climate change is expected to affect alpine stream biodiversity across many levels of biological resolution from micro- to macroscopic organisms and genes to communities. Herein, we describe the current state of alpine stream biology from an organism-focused perspective. We begin by reviewing seven standard and emerging approaches that combine to form the current state of the discipline. We follow with a call for increased synthesis across existing approaches to improve understanding of how these imperiled ecosystems are responding to rapid environmental change. We then take a forward-looking viewpoint on how alpine stream biologists can make better use of existing data sets through temporal comparisons, integrate remote sensing and geographic information system (GIS) technologies, and apply genomic tools to refine knowledge of underlying evolutionary processes. We conclude with comments about the future of biodiversity conservation in alpine streams to confront the daunting challenge of mitigating the effects of rapid environmental change in these sentinel ecosystems. © 2017 Cambridge Philosophical Society.

Full Text Available Ecological restoration is a very active area in ecology and of great importance for ecosystems management. Despite of being a relatively young discipline, the classical concepts of restoration seem, at present, impractical considering the great challenges generated by modification and destruction of ecosystems. This is due to anthropic activities (deforestation, change of land use, pollution and global climate change. In the classic definition of restoration, the objective is to recover the degraded ecosystem to the same conditions of a historical reference state. However, nowadays the ecosystems return to a state prior to the disturbances seems unviable, because the thresholds of resilience have already been overcome. Additionally, climate change is causing environmental changes at an unprecedented rate. For this reason, ecological restoration needs to unite efforts of diverse actors to recover ecosystems that can be sustainable and functional in the future, where the species could be able to tolerate the environmental conditions that will exist in the long term. Assisted migration has been proposed as a conservation strategy; it is defined as the translocation of species to new locations outside their known range of distribution. In the current context of loss of diversity and ecosystems, this strategy could be fundamental for the formation of new communities that can later become novel ecosystems where species that are fundamental to the dynamics of ecosystems can persist and, at the same time, recover function, structure and resilience.
Full Text Available During the past few decades, the Swedish spatial planning system has experienced numerous problems and challenges. In particular, there have been changes in legislation and an increased neoliberalisation of planning that gives private actors a larger influence over the planning processes in Sweden. In this article, we analyse these changes through the lenses of collaborative and neoliberal planning in order to illuminate the shifting power relations within spatial planning in Sweden. We analyse the changes of power relations from three dimensions of power based on interviews with different kinds of planners throughout Sweden. We show that power relations in the Swedish spatial planning system have shifted and that neoliberalisation and an increased focus on collaborative planning approaches have made spatial planning more complex in recent decades. This has led to a change of role for planners form actual planners to collaborators. We conclude that market-oriented planning (neoliberal planning and collaborative planning have made it more difficult for spatial planners in Sweden to work towards sustainable urban futures.

Subsequent to the release of the 2007 Report of the Intergovernmental Panel on Climate Change, the Province of British Columbia in Canada became an international leader in the development and implementation of innovative climate change mitigation policies. These include, but are not limited to, the 2008 Greenhouse Gas Reductions Target Act, the 2008 Carbon Tax Act and the 2010 Clean Energy Act. British Columbia's Cleantech sector quickly responded to, and thrived as a result of, the signal sent by government to the market. But with a change in Premier in 2011 came a change in priorities. A number of the previous initiatives have either been weakened or no longer followed through with as the Province sets its vision of being a major exporter of Liquified Natural Gas. As a member of the British Columbia Climate Action Team set up by Premier Gordon Campbell in 2007 to provide advice to government on a variety of policy-related matters, I was fortunate to be able to watch first hand as the Province aggressively moved towards reducing its Greenhouse gas emissions. Rather than stand on the sidelines as the government lost its direction on the climate file I chose to run with the BC Green Party in the 2013 provincial election. I was subsequently elected as a Member of the Legislative Assembly representing the constituents of Oak Bay Gordon Head. While science can and should inform policy deliberations, in and of itself, science cannot and should not prescribe policy outcomes. Whether or not we deal with today's challenge of climate change boils down to a question of intergeneration equity. Does the present generation owe anything to future generations in terms of the quality of the environment that they inherit? Many of today's elected decision-makers are focused on short-term decision-making. Yet those who will be affected by the consequences of these decisions are not part of the decision making process — hence the political conundrum. In this presentation I detail

foci emerged in discussions within the NEESPI community during the past 20 months. Presentation will provide justification of these foci and approach examples addressing them. The societal challenges, particularly the socio-economic challenges are the top priority in most of them. Throughout the NEESP Initiative duration, support for it studies has been provided by different national and international Agencies of the United States (in particular, the NASA Land Cover and Land Use Change Program), the Russian Federation (in particular, the Ministry of Education and Science, e.g., mega-grant 14.B25.31.0026), European Union, Japan, and China. After the NEFI White Paper release, we anticipate a similar kind of support for this new Initiative.
Full Text Available Abstract Background Electrodermal reactions (EDRs can be attributed to many origins, including spontaneous fluctuations of electrodermal activity (EDA and stimuli such as deep inspirations, voluntary mental activity and startling events. In fields that use EDA as a measure of psychophysiological state, the fact that EDRs may be elicited from many different stimuli is often ignored. This study attempts to classify observed EDRs as voluntary (i.e., generated from intentional respiratory or mental activity or involuntary (i.e., generated from startling events or spontaneous electrodermal fluctuations. Methods Eight able-bodied participants were subjected to conditions that would cause a change in EDA: music imagery, startling noises, and deep inspirations. A user-centered cardiorespiratory classifier consisting of 1 an EDR detector, 2 a respiratory filter and 3 a cardiorespiratory filter was developed to automatically detect a participant's EDRs and to classify the origin of their stimulation as voluntary or involuntary. Results Detected EDRs were classified with a positive predictive value of 78%, a negative predictive value of 81% and an overall accuracy of 78%. Without the classifier, EDRs could only be correctly attributed as voluntary or involuntary with an accuracy of 50%. Conclusions The proposed classifier may enable investigators to form more accurate interpretations of electrodermal activity as a measure of an individual's psychophysiological state.

The ecological effects of global warming are expected to be large, but are proving difficult and costly to measure. This has led to a growing interest in using sentinel species as early warning indicators of impending climate change effects on entire ecosystems, raising awareness of the importance of verifying that such conservation shortcuts have sound biological foundations. A recent large-scale warming event in the North Pacific Ocean of unprecedented magnitude and duration allowed us to evaluate the sentinel status of giant kelp, a coastal foundation species that thrives in cold, nutrient-rich waters and considered sensitive to warming. Here we show that giant kelp did not presage ecosystem effects of extreme warming off southern California despite its expected vulnerability. Fluctuations in the biomass of giant kelp, understory algae, invertebrates and fish remained within historical ranges despite 34 months of above average temperatures and below average nutrients. Sea stars and sea urchins were exceptions, plummeting due to disease outbreaks linked to the warming. Our results challenge the IPCC predictions about the vulnerability of kelp-dominated systems to extreme warming events and question their use as early indicators of climate change. The resilience of giant kelp to unprecedented warming not only questions our understanding of kelp ecology, but exposes the risk of relying on supposed sentinel species that are assumed to be very sensitive to climate change.
Full Text Available A shift is taking place within environmental governance that draws attention to modes and instruments that respond to system dynamics, uncertainty, and contested values. Adaptive comanagement is one process being advanced to make governance operational as it emphasizes collaboration among diverse actors, functions across scales and levels, and fosters learning though iterative feedback. Although extensive experience with adaptive comanagement has been gained in relation to other environmental and resource issues, its potential contribution to the governance of adaption is largely unexplored. This paper probes how adaptive comanagement might offer support to climate change adaptation and identifies gaps in knowledge requiring attention. In drawing upon existing literature and applied experiences, it is argued that adaptive comanagement may contribute to climate change adaptation by building generalized adaptive capacity as well as providing a novel institutional arrangement to generate adaptive responses. At the same time, several questions emerge about adaptive comanagement in this context. Considerations are thus discussed for adaptive comanagement scholarship and application in addressing the challenge of climate change adaptation.

Assessments of the relationships between crop productivity and climate change rely upon a combination of modelling and measurement. As part of this review, this relationship is discussed in the context of crop and climate simulation. Methods for linking these two types of models are reviewed, with a primary focus on large-area crop modelling techniques. Recent progress in simulating the impacts of climate change on crops is presented, and the application of these methods to the exploration of adaptation options is discussed. Specific advances include ensemble simulations and improved understanding of biophysical processes. Finally, the challenges associated with impacts and adaptation research are discussed. It is argued that the generation of knowledge for policy and adaptation should be based not only on syntheses of published studies, but also on a more synergistic and holistic research framework that includes: (i) reliable quantification of uncertainty; (ii) techniques for combining diverse modelling approaches and observations that focus on fundamental processes; and (iii) judicious choice and calibration of models, including simulation at appropriate levels of complexity that accounts for the principal drivers of crop productivity, which may well include both biophysical and socio-economic factors. It is argued that such a framework will lead to reliable methods for linking simulation to real-world adaptation options, thus making practical use of the huge global effort to understand and predict climate change.

National parks and nature reserves are set aside to preserve certain ecosystems, reflecting species distributions at a moment in time. Changing climate and fire dynamics can mean that the species most suited to that area are different, leading new tree species to 'invade' the conservation areas. Pittosporum undulatum is an invasive tree native tree species with a natural range from southeast Queensland to Eastern Victoria, Australia. Soon after European settlement this species became a popular ornamental tree in gardens and was planted outside of its natural range across the continent and introduced to the USA (where it is known as Victorian Box), the Hawaiian Islands, Jamaica, southern Africa and the Azores. The reason this is important is because high density of P. undulatum lead to reduced biodiversity and often the complete suppression of regeneration of exiting forest trees. In Australia, changes in fire dynamics have played a major part in its in dominance. New strategies for forest management were proposed by Gleadow an Ashton in the 1980s, but lack of action has led us to predict that the entire Dandenong Ranges, near Melbourne, will be invaded within 25 years resulting in the loss of a major recreational and conservation area. This is a model of the type of problems that can be expected as the climate envelope for species changes in the coming century, challenging the very concept of a "native ".

Full Text Available Geotechnical asset owners need to know which parts of their asset network are vulnerable to climate change induced failure in order to optimise future investment. Protecting these vulnerable slopes requires monitoring systems capable of identifying and alerting to asset operators changes in the internal conditions that precede failure. Current monitoring systems are heavily reliant on point sensors which can be difficult to interpret across slope scale. This paper presents challenges to producing such a system and research being carried out to address some of these using electrical resistance tomography (ERT. Experimental results show that whilst it is possible to measure soil water content indirectly via resistivity the relationship between resistivity and water content will change over time for a given slope. If geotechnical parameters such as pore water pressure are to be estimated using this method then ERT systems will require integrating with more conventional geotechnical instrumentation to ensure correct representative information is provided. The paper also presents examples of how such data can be processed and communicated to asset owners for the purposes of asset management.

Geoscientific analyses of Earth observation data typically involve a long path from data acquisition to scientific results and conclusions. Before starting the actual processing, scenes must be downloaded from the providers' platforms and the computing infrastructure needs to be prepared. The computing environment often requires specialized software, which in turn might have lots of dependencies. The software is often highly customized and provided without commercial support, which leads to rather ad-hoc systems and irreproducible results. To let other scientists reproduce the analyses, the full workspace including data, code, the computing environment, and documentation must be bundled and shared. Technologies such as virtualization or containerization allow for the creation of identical computing environments with relatively little effort. Challenges, however, arise when the volume of the data is too large, when computations are done in a cluster environment, or when complex software components such as databases are used. We discuss these challenges for the example of scalable Land use change detection on Landsat imagery. We present a reproducible implementation that runs R and the scalable data management and analytical system SciDB within a Docker container. Thanks to an explicit container recipe (the Dockerfile), this enables the all-in-one reproduction including the installation of software components, the ingestion of the data, and the execution of the analysis in a well-defined environment. We furthermore discuss possibilities how the implementation could be transferred to multi-container environments in order to support reproducibility on large cluster environments.

Acutely ill patients are often treated on site instead of being transported to hospital, so wide-ranging professional competence is required from staff. The aim of this study was to describe and produce new information about out-of-hospital emergency care providers' competence, skills and willingness to engage in self-development activities, and to uncover challenges experienced by care providers in the midst of changing work practices. A quantitative questionnaire was sent to out-of-hospital emergency care providers (N = 142, response rate 53%) of one Finnish hospital district. Data were analysed using spss for Windows 22 software. Almost all respondents found their work interesting and their ability to work independently sufficient. The majority found the work meaningful. Almost 20% felt that work was dominated by constant rush, and 40%, more than half of 25-year-olds but <10% of over 45-years-olds, found the work physically straining. The majority indicated that they had a sufficient theoretical-practical basis to perform their regular duties, and more than one-third felt that they had sufficient skills to deal with multiple patient or disaster situations. Over 20% stated that they were unsure about performing new or infrequent procedures. A number of factors experienced as challenging were revealed. The results provide a basis for improving care providers' initial and further training. © 2017 Nordic College of Caring Science.

The UK's Higher Education Academy Subject Centre for Geography, Earth and Environmental Sciences (GEES) is currently running a project entitled ‘C-Change in GEES: Open licensing of climate change and sustainability resources in the Geography, Earth and Environmental Sciences' as part of a national Open Educational Resource project. The C-Change project aims to explore the challenges involved in ‘repurposing' existing teaching materials on the topics of climate change and sustainability to make them open access. This project has produced an open access resource of diverse climate change and sustainability-related teaching materials across the subjects of Geography, Earth and Environmental Sciences. The process of repurposing existing face-to-face teaching resources requires consideration of a wide variety of issues including the Intellectual Property Rights (IPR) associated with images and other material included in the teaching resources, in addition to issues of quality, accessibility and usability of resources. Open access education is an issue that will have implications across the whole of the organizational structure of a university, from legal advisors with commitments to University research and enterprise activities, to the academics wishing to produce open access resources, through to all levels of senior management. The attitudes, concerns and openness to Open Educational Resources of stakeholders from all positions within a HE institution will have implications for the participation of that institution within the OER movement. The many barriers to the whole-scale adoption of Open Educational Resources within the UK Higher Education system and the willingness of UK Higher Education Institutions to engage in the OER movement include institutional perspectives on the IPR of teaching materials developed by members of staff within the institution and financial viability, in addition to more sceptical attitudes of potential contributors.

In the context of consent, "voluntariness" refers to a patient's right to make health care choices free of any undue influence. However, a patient's freedom to make choices can be compromised by internal factors such as pain and by external factors such as force, coercion and manipulation. In exceptional circumstances--for example, involuntary admission to hospital--patients may be denied their freedom of choice; in such circumstances the least restrictive means possible of managing the patient should always be preferred. Clinicians can minimize the impact of controlling factors on patients' decisions by promoting awareness of available choices, inviting questions and ensuring that decisions are based on an adequate, unbiased disclosure of the relevant information.

Hair cortisol concentrations (HCC) are assumed to provide a stable, integrative marker of long-term systemic cortisol secretion. However, contrary to this assumption, some recent observations have raised the possibility that HCC may be subject to acute influences, potentially related to cortisol incorporation from sweat. Here, we provide a first detailed in vivo investigation of this possibility comprising two independent experimental studies: study I (N=42) used a treadmill challenge to induce sweating together with systemic cortisol reactivity while in study II (N=52) a sauna bathing challenge induced sweating without systemic cortisol changes. In both studies, repeated assessments of HCC, salivary cortisol, cortisol in sweat and individuals' sweating rate (single assessment) were conducted on the experimental day and at a next-day follow-up. Results across the two studies consistently revealed that HCC were not altered by the acute interventions. Further, HCC were found to be unrelated to acute salivary cortisol reactivity, sweat cortisol levels, sweating rate or the time of examination. In line with previous data, cortisol levels in sweat were strongly related to total salivary cortisol output across the examined periods. The present results oppose recent case report data by showing that single sweat-inducing interventions do not result in acute changes in HCC. Our data also tentatively speak against the notion that cortisol in sweat may be a dominant source of HCC. Further, our findings also indicate that HCC are not subject to diurnal variation. This research provides further support for hair cortisol analysis as a marker of integrated long-term systemic cortisol secretion. Copyright © 2015 Elsevier Ltd. All rights reserved.

In the coming decades a changing climate and natural hazards will likely increase the vulnerability of agricultural and other food production infrastructures, posing increasing treats to industrialized and developing economies. While food security concerns affect us globally, the huge differences among countries in stocks, population size, poverty levels, economy, technologic development, transportation, health care systems and basic infrastructure will pose a much larger burden on populations in the developing and less developed world. In these economies, increase in the magnitude, duration and frequency of droughts, floods, hurricanes, rising sea levels, heat waves, thunderstorms, freezing events and other phenomena will pose severe costs on the population. For this presentation, we concentrate on a geophysical perspective of the problems, tools available, challenges and short and long-term perspectives. In many instances, a range of natural hazards are considered as unforeseen catastrophes, which suddenly affect without warning, resulting in major losses. Although the forecasting capacity in the different situations arising from climate change and natural hazards is still limited, there are a range of tools available to assess scenarios and forecast models for developing and implementing better mitigation strategies and prevention programs. Earth observation systems, geophysical instrumental networks, satellite observatories, improved understanding of phenomena, expanded global and regional databases, geographic information systems, higher capacity for computer modeling, numerical simulations, etc provide a scientific-technical framework for developing strategies. Hazard prevention and mitigation programs will result in high costs globally, however major costs and challenges concentrate on the less developed economies already affected by poverty, famines, health problems, social inequalities, poor infrastructure, low life expectancy, high population growth

The author conducted indepth studies – using the Multidimensional Statistical Analysis, the Strategic Analyses, as well as the Grounded Theory Method. Findings: The changes in the strategies of the Top-TNCs proceeded according to a uniform scheme – the authorial Model of Business Integration was presented as the standard for TNCs adjusting to further challenges posed by the evolving global economy. Based on the survey, the author identified universal pillars of the Top-TNC strategy: glocalization, business networking, orchestration and coopetition. Implications & Recommendations: TNCs desiring to engage in the most efficient system for creating international competitiveness should apply the following tactics: link globalization and regionalization, build a multi-level relationship system, creatively combine various types of organizational and social structures, simultaneously employ cooperation and competition. Contribution & Value Added: The work sought to provide evidence that regardless of the area of activity, the pillars of strategy for Top-TNCs are the same in terms of the core, but are often implemented in different forms. The author proposes the original concept for assessing the competitiveness of network enterprises – the Synthetic Indicator of Creation of Added Value.

By June 2005, when shipments of spent fuel for reprocessing from Germany are concluded, the NTL11 flask type will have been responsible for transporting a total of 1500 tonnes of heavy metal in the form of spent fuel. Excluding domestic transports in France and the UK, this represents 25% of the total European spent fuel transported for reprocessing since the flasks came into service in 1977. Approximately 40% of the total for the flask type will have been transported to BNFL's Sellafield facility, the remainder to Cogema at La Hague. The NTL11 flask can justifiably be described as being the workhorse of BNFL's European spent fuel transport business. The NTL11 flask started life under the ownership of Nuclear Transport Limited, an associate company of BNFL, and in recent years the original fleet of five flasks has been absorbed into the BNFL inventory. A recent build programme has seen a further four flasks added to the fleet, an expedient measure to cope with the additional transport requirements imposed by the need to meet the June 2005 deadline for the removal of contracted fuels from Germany. While there have been certain evolutionary changes affecting the package design, there have also been more significant changes in the Design Safety Case. These have sometimes been necessary to meet regulatory changes, or the challenges posed by the regulators. In other cases advantage has been taken of improvements in analytical techniques to demonstrate increased margins of operational safety. Where possible those margins have also been increased by other means, such as taking advantage of commercial trends to reduce package thermal loads. The NTL11 flask was designed around the reactor and fuel characteristics prevailing in the 1970's. Over the lifetime of the flask the responsible engineering teams have faced and met the successive challenges to develop the capability of the Package to face the changing requirements of the industry and the Transport

acquire advice and information "on the go" were valued. Context-sensing capabilities and social media features tended to be considered unnecessary and off-putting. This study provided insight into the opportunities and challenges involved in delivering health-related behavioral interventions through smartphone apps. The findings suggested a number of valued features and characteristics that app developers may wish to consider when creating health behavior apps. Findings also highlighted several major challenges that appeared to need further consideration and research to ensure the development of effective and well-accepted behavior change apps.

Few regions of the world are at higher risk for environmental disasters than the Pacific Island countries and territories. During 2004 and 2005, the top public health leadership from 19 of 22 Pacific Island countries and territories convened 2 health summits with the goal of developing the world's first comprehensive regional strategy for sustainable disaster risk management as applied to public health emergencies. These summits followed on the objectives of the 1994 Barbados Plan of Action for the Sustainable Development of Small Island Developing States and those of the subsequent Yokohama Strategy and Plan of Action for a Safer World. The outputs of the 2004 and 2005 Pacific Health Summits for Sustainable Disaster Risk Management provide a detailed description of challenges and accomplishments of the Pacific Island health ministries, establish a Pacific plan of action based upon the principles of disaster risk management, and provide a locally derived, evidence-based approach for many climate change adaptation measures related to extreme weather events in the Pacific region. The declaration and outputs from these summits are offered here as a guide for developmental and humanitarian assistance in the region (and for other small-island developing states) and as a means for reducing the risk of adverse health effects resulting from climate change.

Full Text Available Professional football has been going through a period of unprecedented economic growth since the ’90s. Football ventures are increasingly becoming medium-sized companies. There have also been organizational changes, reflected in changes in the legal forms of professional football clubs, and in the use of modern controlling, planning, risk and financial management. Important questions remain unanswered with regard to the financing of football clubs, such as the impact of risks or the market value of capital costs. In addition to liquidity and the above, the acceptance of the determinational dependence of certain capital funds on sports results and the development of a strategy suitable for the optimal target system are also important requirements. In this article, we would like to present the answers football companies have given to the challenges they have been facing which affect their organisational system. In the light of international comparison, we examine the status of Hungarian football, which was once world famous and enjoyed better times in the past.
The public sector is facing turbulent times and this challenges nurses, who are expected to serve both patient interests and the efficiency drives of their organisations. In the context of implementing person-centred health policy, this paper explores the evolving role of front-line nurses as leaders and champions of change. Nurses can be seen to have some autonomy in health-care delivery. However, they are subject to systems of social control. In implementing person-centred policy, nurses can be seen to be doing the best they can within a constrained environment. A survey of nursing practice in person-centred health-policy implementation is presented. Despite much being written about managing health-professional resistance to policy implementation, there is a gap between what is being asked of nurses and the resources made available to them to deliver. In this milieu, nurses are utilising their discretion and leading from the front-line in championing change. Empowering nurses who seek to lead patient involvement could be the key to unlocking health-care improvement. Health services tend to be over-managed and under-led and there is a need to harness the potential of front-line nurses by facilitating leadership development through appropriate organisational support. © 2015 John Wiley & Sons Ltd.
discussion about climate change as a concerted multilevel operation is opened up. A normative theoretical answer to the question of how to move forward is provided. It is argued that the scalar discourses analysed do not mesh and create a balance between the different rationalities of the three dominating rationalities in environmental policymaking: scientific, economic, and communicative. Today's environmental challenges, globally, nationally, and locally, demand a better understanding of the need to combine different rationalities and create alliances with different actors. The perspective brought forward suggests ways that discourses can be used as tool for a better realisation of policy goals. Six articles are analysed, illustrating the central arguments.

Climate change and accelerating socioeconomic developments increasingly challenge flood-risk management in the Vietnamese Mekong River Delta-a typical large, economically dynamic and highly vulnerable delta. This study identifies and addresses the emerging challenges for flood-risk management. Furthermore, we identify and analyse response solutions, focusing on meaningful configurations of the individual solutions and how they can be tailored to specific challenges using expert surveys, content analysis techniques and statistical inferences. Our findings show that the challenges for flood-risk management are diverse, but critical challenges predominantly arise from the current governance and institutional settings. The top-three challenges include weak collaboration, conflicting management objectives and low responsiveness to new issues. We identified 114 reported solutions and developed six flood management strategies that are tailored to specific challenges. We conclude that the current technology-centric flood management approach is insufficient given the rapid socioecological changes. This approach therefore should be adapted towards a more balanced management configuration where technical and infrastructural measures are combined with institutional and governance resolutions. Insights from this study contribute to the emerging repertoire of contemporary flood management solutions, especially through their configurations and tailoring to specific challenges.

Previous studies suggest that challenge of most wine-sensitive asthmatic patients may not result in a reduction in forced expiratory volume in 1 s (FEV(1)). The aim of this study was to assess whether changes in bronchial hyperresponsiveness (BHR) occur following wine challenge of asthmatic patients who report sensitivity to wine, and whether such changes could help clarify the role of sulphite additives in wine-induced asthmatic responses. Eight self-reporting wine-sensitive asthmatic patients completed double-blind challenges with high- and low-sulphite wines on separate days. FEV(1) and histamine PC(20) were measured before and after consumption of 150 mL of wine. None of the eight subjects demonstrated a clinically significant >or=15%) reduction in FEV(1) following challenge with either high- or low-sulphite wine. In contrast, one patient demonstrated clinically significant increase in BHR following challenge with both high- and low-sulphite wines, and a smaller increase in BHR following placebo challenge. A second patient showed a significant increase, while another showed a significant decrease in BHR following challenge with low-sulphite wine. A fourth patient showed borderline increases in BHR following challenge with both high- and low-sulphite wines. Although changes in BHR, in the absence of reductions in FEV(1), were observed in some asthmatic patients following wine challenge, these changes were not consistent with a single aetiology. Consequently, this study did not support a major role for the sulphite additives in wine-induced asthmatic responses in the patients studied. The aetiology of wine-induced asthma is likely to be complex and appears to vary among individuals who are sensitive to these drinks.

The development of numerical models of river morpho-dynamics is hampered by the lack of high-resolution data at multiple time and space scales for model validation. Such data are especially challenging to obtain for sand-bed braided rivers that typically have multiple channels of varying depth and contain rapidly migrating low-relief bar-lobes and dunes. This paper reports on the efforts to meet these challenges using repeat UAV surveys and plane sorties to quantify morphological change and bedform migration rates along the South Saskatchewan River, Canada. The South Saskatchewan River, near Outlook (SK Province) is 600 m wide with very well sorted medium sand (D50 = 0.3 mm) and negligible clay. The Gardiner Dam, 20 km upstream of the study reach, traps much of the very fine sediment so that the waters are clear at low flow and therefore the river bed is entirely visible. Fieldwork campaigns in 2015 and 2016 captured: (i) 1:5000 aerial colour photographs over a 17.5 km reach; (ii) high temporal frequency repeat imagery, obtained using quadcopter and fixed-wing UAV platforms for multiple 100 x 500 m sub-reaches. Plane images were processed via Structure from Motion (SfM) photogrammetric techniques using Pix4D and supporting ArcGIS and Global Mapper analysis. The resulting point cloud was corrected for tilt and filtered in MATLAB at multiple spatial scales to remove noise. Elevations in sub-aqueous zones were obtained using a statistical model, relating image brightness to water depth, developed using single beam echo-sounder data collected near to the flight time. The final DSM for the plane imagery combines these two methods and has a 0.5 m spatial resolution with vertical accuracy of 6 cm. UAV imagery is also processed using Pix4D with application of a diffraction water depth correction, required due to the lower flight height, and gives a resulting vertical accuracy of 2 cm. Initial results highlight the following issues: (i) there are a series of technical

Full Text Available Studies have demonstrated ways in which climate-related shifts in the distributions and relative abundances of marine species are expected to alter the dynamics and catch potential of global fisheries. While these studies assess impacts on large-scale commercial fisheries, few efforts have been made to quantitatively project impacts on small-scale subsistence and commercial fisheries that are economically, socially and culturally important to many coastal communities. This study uses a dynamic bioclimate envelope model to project scenarios of climate-related changes in the relative abundance, distribution and richness of 98 exploited marine fishes and invertebrates of commercial and cultural importance to First Nations in coastal British Columbia, Canada. Declines in abundance are projected for most of the sampled species under both the lower (Representative Concentration Pathway [RCP] 2.6 and higher (RCP 8.5 emission scenarios (-15.0% to -20.8%, respectively, with poleward range shifts occurring at a median rate of 10.3 to 18.0 km decade(-1 by 2050 relative to 2000. While a cumulative decline in catch potential is projected coastwide (-4.5 to -10.7%, estimates suggest a strong positive correlation between the change in relative catch potential and latitude, with First Nations' territories along the northern and central coasts of British Columbia likely to experience less severe declines than those to the south. Furthermore, a strong negative correlation is projected between latitude and the number of species exhibiting declining abundance. These trends are shown to be robust to alternative species distribution models. This study concludes by discussing corresponding management challenges that are likely to be encountered under climate change, and by highlighting the value of joint-management frameworks and traditional fisheries management approaches that could aid in offsetting impacts and developing site-specific mitigation and adaptation

The Arctic region will warm more rapidly than the global mean, influencing dramatically the northern ecosystems. Simultaneously, our societies transform towards urbanized, highly educated, service-based culture, where a decreasing population will gain its livelihood from primary production. We study various ecosystem interactions in a changing climate and integrate these with reindeer husbandry and the indigenous Sámi culture dependent on it1. Potential climate impacts include the transformation of arctic-alpine tundra to dense scrubland with conceivable consequences to reindeer husbandry, but also global warming due to decreasing albedo. The social-ecological system (SES) of reindeer husbandry includes administrative and ecological processes that do not always correspond (Figure 1). Consequently, management priorities and administration may conflict with local social and ecological processes, bringing about risks of environmental degradation, loss of biodiversity and defeat of traditional livelihoods. We hypothesize the plausibility to support the indigenous reindeer herding livelihood against rapid external changes by utilizing the migratory reindeer grazing system of the Sámi as a management tool for sustaining the high-albedo tundra and mitigating global warming. Our first-of-a-kind satellite-based high resolution vegetation map covering Northern Fennoscandia allows detailed management plans. Our ecological research demonstrates the important role of herbivory on arctic vegetation communities. Interactive workshops with reindeer herders offer indigenous knowledge of state and changes of the ecosystems, and reflect the threats and expectations of the herders. We are currently building models of the complex social-ecological system of Northern Fennoscandia and will report the first findings of the exercise. 1 www.ncoetundra.utu.fi Figure 1.

The present study tested the hypothesis that the change in state negative affect (measured as perceived stress) after cognitive challenge moderates the relationship of trait anxiety and anger to vagal recovery from that challenge. Cardiac vagal control (assessed using heart rate variability) and respiratory rate were measured in a sample of 905 participants from the Midlife in the United States Study. Cognitive challenges consisted of computerized mental arithmetic and Stroop color-word matching tasks. Multiple regression analyses controlling for the effects of the demographic, lifestyle, and medical factors influencing cardiac vagal control showed a significant moderating effect of change in perceived stress on the relationship of trait anxiety to vagal recovery from cognitive challenges (Beta = .253, p= .013). After adjustment for respiratory rate, this effect became marginally significant (Beta = .177, p= .037). In contrast, for the relationship of trait anger to vagal recovery, this effect was not significant either before (Beta = .141, p=.257) or after (Beta = .186, p=.072) adjusting for respiratory rate. Secondary analyses revealed that among the individuals with higher levels of trait anxiety, greater reductions in perceived stress were associated with greater increases in cardiac vagal control after the challenge. In contrast, among the individuals with lower levels of trait anxiety, changes in perceived stress had no impact on vagal recovery. Therefore, change in perceived stress moderates the relationship of trait anxiety, but not trait anger, to vagal recovery from cognitive challenge. PMID:21945037
Full Text Available The functional reasons for isoprene emission are still a matter of hot debate. It was hypothesized that isoprene biosynthesis evolved as an ancestral mechanism in plants adapted to high water availability, to cope with transient and recurrent oxidative stresses during their water-to-land transition. There is a tight association between isoprene emission and species hygrophily, suggesting that isoprene emission may be a favorable trait to cope with occasional exposure to stresses in mesic environments. The suite of morpho-anatomical traits does not allow a conservative water use in hygrophilic mesophytes challenged by the environmental pressures imposed or exacerbated by drought and heat stress. There is evidence that in stressed plants the biosynthesis of isoprene is uncoupled from photosynthesis. Because the biosynthesis of isoprene is costly, the great investment of carbon and energy into isoprene must have relevant functional reasons. Isoprene is effective in preserving the integrity of thylakoid membranes, not only through direct interaction with their lipid acyl chains, but also by up-regulating proteins associated with photosynthetic complexes and enhancing the biosynthesis of relevant membrane components, such as mono- and di-galactosyl-diacyl glycerols and unsaturated fatty acids. Isoprene may additionally protect photosynthetic membranes by scavenging reactive oxygen species. Here we explore the mode of actions and the potential significance of isoprene in the response of hygrophilic plants when challenged by severe stress conditions associated to rapid climate change in temperate climates, with special emphasis to the concomitant effect of drought and heat. We suggest that isoprene emission may be not a good estimate for its biosynthesis and concentration in severely droughted leaves, being the internal concentration of isoprene the important trait for stress protection.

Increasing temperatures and snow scarce winter seasons pose a big challenge for the winter tourism industry. Changing natural snow reliability influences tourism demand and ski area operators are faced with an enhanced need of technical snow production. The goal of the present research work is to analyze the economic effects of technical snow production under future climate conditions. Snowmaking as an adaptation strategy to climate change impacts on the ski tourism industry is already taken into consideration in several studies from a scientific perspective concerning snowmaking potentials under future climate conditions and the impacts on ski season length (e.g. Scott et al. 2003; Scott & McBoyle 2007; Hennessy et al. 2008; Steiger 2010). A few studies considered economic aspects of technical snowmaking (e.g. Teich et al. 2007; Gonseth 2008). However, a detailed analysis of the costs and benefits of snowmaking under future climate and snow conditions based on sophisticated climate and snow models has not been carried out yet. The present study addresses the gap of knowledge concerning the economic profitability of prospective snowmaking requirements under future climate scenarios. We carry out a detailed cost-revenue analysis of snowmaking under current and future climate conditions for a case study site in Styria (Austria) using dynamic investment models. The starting point of all economic calculations is the daily demand for artificial snow that determines the requirements for additional snowmaking investments and additional operating costs. The demand for artificial snow is delivered by the snow cover model AMUNDSEN (see Strasser et al. 2011) and is driven by four climate scenarios. Apart from future climate conditions the profitability of snowmaking depends on changes in costs and visitor numbers. The results of a ski tourism demand model analyzing daily visitor numbers and their dependencies of prevailing weather conditions enter the cost-revenue analysis of

Impaired cerebrovascular reserve in chronic steno-occlusive disease has been shown to be associated with poor leptomeningeal collaterals (LMCs) on digital subtraction angiography and increased stroke risk. We examined the relationship between the degree of LMCs and the flow change with Diamox challenge measured using quantitative magnetic resonance angiography (QMRA). Patients with steno-occlusion in the internal carotid artery or middle cerebral artery (MCA) at our institution between 2007 and 2013 were retrospectively studied. Intracranial flows were obtained using QMRA, and flow change with Diamox (QMRAΔd) was calculated as follows: ([flow after Diamox-flow before Diamox]/[flow before Diamox])×100%. Poor LMC was defined as grade 1 or 2, and robust LMC was defined as grade 3 or 4 based on the ASITN/SIR (American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology) grading system on digital subtraction angiography. Thirty-eight patients had angiographic and flow data. Ipsilateral MCA QMRAΔd was significantly lower versus the contralateral side (flow, 85.5 versus 135.9 mL/min; P<0.001 and QMRAΔd, 24.0% versus 45.6%; P=0.01). If LMCs were robust (n=12), MCA QMRAΔd was significantly higher (21.4% versus -26.8%; P=0.04) compared with patients with poor LMC (n=4). We show that patients with more robust LMC have better MCA QMRAΔd. Therefore, QMRAΔd may be used for the functional assessment of LMC as a surrogate for cerebrovascular reserve in chronic internal carotid artery or MCA steno-occlusive disease. © 2016 American Heart Association, Inc.

Teachers need an understanding of the nature of science (NOS) to enable them to incorporate NOS into their teaching of science. The current study examines the usefulness of a strategy for challenging or changing teachers' understandings of NOS. The teachers who participated in this study were 10 initial teacher education chemistry students and six experienced teachers from secondary and primary schools who were introduced to an explicit and reflective activity, a dramatic reading about a historical scientific development. Concept maps were used before and after the activity to assess teachers' knowledge of NOS. The participants also took part in a focus group interview to establish whether they perceived the activity as useful in developing their own understanding of NOS. Initial analysis led us to ask another group, comprising seven initial teacher education chemistry students, to take part in a modified study. These participants not only completed the same tasks as the previous participants but also completed a written reflection commenting on whether the activity and focus group discussion enhanced their understanding of NOS. Both Lederman et al.'s (Journal of Research in Science Teaching, 39(6), 497-521, 2002) concepts of NOS and notions of "naive" and "informed" understandings of NOS and Hay's (Studies in Higher Education, 32(1), 39-57, 2007) notions of "surface" and "deep" learning were used as frameworks to examine the participants' specific understandings of NOS and the depth of their learning. The ways in which participants' understandings of NOS were broadened or changed by taking part in the dramatic reading are presented. The impact of the data-gathering tools on the participants' professional learning is also discussed.

Current pharmacological and psychological treatments for disorders of emotional memory only dampen the affective response while leaving the original fear memory intact. Under adverse circumstances, these original memories regain prominence, causing relapses in many patients. The (re)discovery in neuroscience that after reactivation consolidated fear memories may return to a transient labile state, requiring a process of restabilization in order to persist, offers a window of opportunity for modifying fear memories with amnestic agents. This process, known as memory reconsolidation, opens avenues for developing a revolutionary treatment for emotional memory disorders. The reconsolidation intervention challenges the dominant pharmacological and psychological models of treatment: it is only effective when the amnestic drug is given in conjunction with memory reactivation during a specific time window, and a modification of cognitive processes is a boundary condition for changing fear. Notwithstanding the dramatic effects of targeting memory reconsolidation in the laboratory (i.e. proof of principle), the greatest hurdle to overcome is that the success of the manipulation depends on subtle differences in the reactivation procedure. These experimental parameters cannot be easily controlled in clinical practice. In harnessing the clinical potential of memory reconsolidation, a heuristic for bi-directionally translating behavioural neuroscience and clinical science is proposed. This article is part of a discussion meeting issue ‘Of mice and mental health: facilitating dialogue between basic and clinical neuroscientists’. PMID:29352032

A new primary science syllabus with strong inquiry focus has been implemented in Singapore since 2008. In this study, we attempted to understand how teachers experience the emphasis of inquiry-based curriculum under the current educational conditions that is routined and highly teacher fronted. We invited 50 pre-service and 41 in-service teachers to participate in survey questionnaires and narratives, reflective writings, and group discussions related to science inquiry which formed our data corpus. Data analysis in the form of thematic coding was carried out using NVivo8, with over 80% inter-rater coding agreement level. Three key aspects of teachers' perceptions of science inquiry were revealed: (1) teachers' responsibilities as facilitators, (2) privileging content knowledge rather than process skills, and (3) pressure of assessment systems in current educational contexts. These understandings bring out conflicts of inquiry teaching between teacher- and student-centredness, content and process, and curriculum and assessment. Based on these teachers' perceptions and dilemmas of inquiry science teaching, the visions and challenges of inquiry science curriculum change against assessment requirements are discussed.

We appreciate the depth and breadth of comments we received. They reflect the interdisciplinary challenge of our inquiry and reassured us of its broad interest. We believe that our target article and the criticisms, elaborations, and extensions of the commentators can be an important contribution to establishing human ultrasociality as a new field of social science inquiry. A few of the commentators questioned our definition of ultrasociality, and we begin our response with an elaboration of that definition and a defense of our argument that human ultrasociality began with agriculture. We then respond to the second major area of controversy, namely, our use of group selection to explain the economic drivers behind the agricultural transition. We then focus on the issue of human intentionality raised by the phenomenon of collective intelligence. The intriguing question is to what extent can an entire culture change its own destiny? We then address the issue of the division of labor raised by a number of commentators. The complex division of labor was both a driver and a defining characteristic of ultrasociality, even though it was present in simpler forms in earlier societies. The remaining issues addressed include energy and complexity, expansion and sustainability, and the accelerating evolution of human ultrasociality. These were raised by only a few commentators, but their importance warrants further elaboration.
Carbon dioxide, methane and nitrous oxides are three greenhouse gases (GHG) that are closely associated with human activities and which contribute to climate change. This publication listed personal GHG emissions from energy use in Canada, in terms of passenger road transportation, space heating and cooling, water heating, appliances and lighting. GHGs are also created through the waste that ends up in landfills. The one-tonne challenge encourages individuals to reduce GHG emissions by using energy efficiently and by making wise consumer choices. This guide presents suggestions to reduce GHGs and to set goals that are reasonable for individual households. The measures can help save money, improve air quality and protect the environment. In terms of driving habits, some effective measures would be to drive 10 per cent less, use the air conditioner sparingly, avoid idling, and choose sustainable transportation such as car-pooling, public transit, cycling, walking or teleworking. In terms of households, some effective measures would be to use energy efficient appliances and light bulbs, weatherproof windows and doors, lower the thermostat, and install ceiling fans and automatic timers. In terms of outside maintenance, some effective measures would be to capture rainwater, recycle, compost, plant trees, and limit the use of gas-powered lawn mowers. A final measure would be to encourage suppliers of green power by switching to wind energy or solar powered electricity, which is produced with fewer or no GHGs or harmful air pollutants. refs., tabs., figs.

With fatiguing exercise, firing of group III/IV muscle afferents reduces voluntary activation and force of the exercised muscles. These afferents can also act across agonist/antagonist pairs, reducing voluntary activation and force in nonfatigued muscles. We hypothesized that maintained firing of group III/IV muscle afferents after a fatiguing adductor pollicis (AP) contraction would decrease voluntary activation and force of AP and ipsilateral elbow flexors. In two experiments (n = 10) we examined voluntary activation of AP and elbow flexors by measuring changes in superimposed twitches evoked by ulnar nerve stimulation and transcranial magnetic stimulation of the motor cortex, respectively. Inflation of a sphygmomanometer cuff after a 2-min AP maximal voluntary contraction (MVC) blocked circulation of the hand for 2 min and maintained firing of group III/IV muscle afferents. After a 2-min AP MVC, maximal AP voluntary activation was lower with than without ischemia (56.2 ± 17.7% vs. 76.3 ± 14.6%; mean ± SD; P muscle afferents from the hand decreased voluntary drive and force of AP. Moreover, this effect decreased voluntary drive and torque of proximal unfatigued muscles, the elbow flexors. Fatigue-sensitive group III/IV muscle nociceptors act to limit voluntary drive not only to fatigued muscles but also to unfatigued muscles within the same limb.

Full Text Available The economic importance of voluntary work has been exceedingly appreciated in the last few decades. This is not surprising at all, because it is highly profitable according to the related estimated data. There are 115,9 million people doing voluntary work only in Europe, which means that they would create the world's 7th biggest economy with EUR 282 billion value creation if they formed an individual state. The organizations know that voluntary work has several advantages apart from the economic benefits. It is profitable both for the society and for the individuals as well. Several researches have proven that voluntary work positively influences the development of the personality, because the key-competencies - such as: co-operation, empathy, solidarity, conflict handling, problem solving, etc. - expected in the labor market can be improved.

Anthropogenic global changes such as rising atmospheric CO2 and temperatures likely will enhance multiple flows of carbon (C) between terrestrial ecosystems and the atmosphere. Understanding the changes these perturbations exert on soil organic C (SOC) pools and fluxes is critical for predicting climate, yet approaches for quantifying changes in SOC cycling suffer from deficiencies. We outline opportunities and challenges of employing stable isotopes in short- and longer-term studies to track soil change, using two forests as case studies. Relatively short-term lab studies employing isotopically labeled compounds can help us elucidate mechanisms of SOC stabilization and loss, but added substrate represents a small fraction of the complex suite of compounds in situ and can induce priming effects. By replacing inputs to a soil profile with labeled photosynthate, we can trace realistic substrates through the soil profile, but the time required for the substrate to become incorporated into all soil organic matter (SOM) fractions is longer than most study periods. These pros and cons are exemplified by two studies. First, tracing 13C-labeled photosynthate applied to temperate pine forest soils for ~10 y demonstrated unequal distribution of 13C label among SOC components, but we discerned likely enhanced activity of microorganisms that turnover recalcitrant SOC compounds in forests exposed to elevated CO2. Here, we describe data consistent with this, emanating from laboratory incubations in which 13C labeled, individual compounds were applied to elevated CO2 and control soils. We demonstrate increased fungal and actinomycete activity with elevated CO2. Here, short-term, lab experiments with simple 13C compounds strengthen longer-term in situ studies. We also employed knowledge gained from these studies to assess how warming will alter flows of SOC. Along a climate transect in boreal forests with similar vegetation and soil types, we applied 13C-labeled photosynthate to

Vector-borne pathogens cause enormous suffering to humans and animals. Many are expanding their range into new areas. Dengue, West Nile and Chikungunya have recently caused substantial human epidemics. Arthropod-borne animal diseases like Bluetongue, Rift Valley fever and African horse sickness pose substantial threats to livestock economies around the world. Climate change can impact the vector-borne disease epidemiology. Changes in climate will influence arthropod vectors, their life cycles and life histories, resulting in changes in both vector and pathogen distribution and changes in the ability of arthropods to transmit pathogens. Climate can affect the way pathogens interact with both the arthropod vector and the human or animal host. Predicting and mitigating the effects of future changes in the environment like climate change on the complex arthropod-pathogen-host epidemiological cycle requires understanding of a variety of complex mechanisms from the molecular to the population level. Although there has been substantial progress on many fronts the challenges to effectively understand and mitigate the impact of potential changes in the environment on vector-borne pathogens are formidable and at an early stage of development. The challenges will be explored using several arthropod-borne pathogen systems as illustration, and potential avenues to meet the challenges will be presented.
The aim of this study was to identify challenges in implementing a physics-before- 10 mathematics curriculum. Obviously, students need to learn necessary mathematics skills in order to develop advanced physics knowledge. In the 2010 high school curriculum in Taiwan, however, grade 11 science students study two-dimensional motion in physics without prior learning experiences of trigonometry in mathematics. The perspectives of three curriculum developers, 22 mathematics and physics teachers, two principals, and 45 science students were obtained by interview. The results of qualitative data analysis revealed six challenges and suggested likely solutions. The national level includes political and social challenges, resolved by respecting teachers as professionals; the teacher level includes knowledge and teaching challenges, resolved by increasing teacher trans-literal capacities; and the student level includes learning and justice challenges, resolved by focusing on students' diverse developments in cross-domain learning.
Consequently, we found that both subjects expressed climbing-up behavior in the initial early period, but only the female who developed typically later, switched to jumping-down behavior with pre-facing to ‘down’ direction. Meanwhile, the male who would have developmental delay later, clearly did not show the switching pattern. The results suggest that the switch timing from involuntary to voluntary movement may be a possible predictor of juvenile and adolescent physiological and psychological retardation. The results also suggest that the primate model allows more methods to be developed for early detection of developmental disabilities that could be utilized in humans to pave the way for interventions and possible psychological or psychiatric treatment.
Full Text Available Market competition creates strategic incentives for firms to communicate private information about their own product quality through certification. Although voluntary certification has recently gained importance in the agricultural industry, information asymmetry is not always completely addressed. This study analyzes how the relative proportion of boundedly rational consumers in the market influences the effectiveness of voluntary certification mechanisms by using a duopoly game model of high- and low-quality firms. The presented results show that a change in the proportion of boundedly rational consumers leads to different certification behaviors and a different market equilibrium. We also find that the existence of boundedly rational consumers is an important factor in the failure of voluntary certification. Indeed, when the relative proportion of such consumers is very high, voluntary certification is ineffective at improving market efficiency.

Recurrent droughts of the last decades have led to severe impacts in forestry and agriculture in the sensitive and vulnerable low-elevation regions of Southeast Europe. Observed impacts are very likely to occur with increasing probability under projected climate conditions throughout the 21st century. In order to suggest options for adaptation and mitigation, a GIS-based Decision Support System is under development in the frame of the joint EU-national research project "Agroclimate". Impact assessments and adaptation support services are based on the simulation results of 12 regional climate models (www.ensembles-eu.org) using the A1B emission scenario until 2100. The development of the Decision Support System requires the balancing of available climatic information and required data for research and economically relevant projection needs of the end users. Here, concrete examples of the development process will be shown for the stepwise analysis and comparison of the followings: 1. Provided climate services: • projected tendencies of temperature and precipitation means and extremes until the end of the 21st century, spread of the simulation results. 2. Required information for climate impact research: • types and characteristics of climate input data, • methods and functions for deriving possible climate change impacts in forestry and agriculture (e.g. on species distribution, growth, production, yield, soil water retention, ground water table, runoff, erosion, evapotranspiration and other ecosystem services and soil properties). 3. Required climate information from the end users' side for developing adaption strategies in the affected sectors: • types of climate indicators, • possible range of the expected impacts (in magnitude and probability). 4. Gaps between climate services and the needs of impact researchers and end users (e.g. spatial and temporal scales, interpretation techniques). Experiences of supporting climate change adaptation in forestry
Full Text Available Voluntary drinking is one of the major determiners of rehydration, especially as regards exercise or workout in the heat. The present study undertakes to search for the effect of voluntary intake of water with different temperatures on fluid balance in Taekwondo athletes. Six young healthy male Taekwondo athletes were dehydrated by moderate exercise in a chamber with ambient temperature at 38-40°C and relative humidity between 20-30%. On four separate days they were allowed to drink ad libitum plane water with the four temperatures of 5, 16, 26, and 58°C, after dehydration. The volume of voluntary drinking and weight change was measured; then the primary percentage of dehydration, sweat loss, fluid deficit and involuntary dehydration were calculated. Voluntary drinking of water proved to be statistically different in the presented temperatures. Water at 16°C involved the greatest intake, while fluid deficit and involuntary dehydration were the lowest. Intake of water in the 5°C trial significantly correlated with the subject's plasma osmolality change after dehydration, yet it showed no significant correlation with weight loss. In conclusion, by way of achieving more voluntary intake of water and better fluid state, recommending cool water (~16°C for athletes is in order. Unlike the publicly held view, drinking cold water (~5°C does not improve voluntary drinking and hydration status.

Cross-education enhances the performance of muscles not directly involved in the chronic conditioning of the muscles in a remote limb. Substantial cross-education occurs after training with eccentric contractions or with contractions evoked by electromyostimulation (EMS). Since during EMS and eccentric contractions, skin and muscle afferents are activated that have excitatory effects on contralateral homologous muscles, it was hypothesized that exercise training with stimulated vs. voluntary eccentric contractions would lead to greater cross-education. Thirty-two women were randomly assigned to a voluntary (Vol), an EMS, or remote EMS (rEMS) exercise group and performed 840 voluntary or stimulated eccentric contractions over 6 weeks. All subjects, including nonexercising controls (Con), were tested pre- and posttraining for maximal voluntary and stimulated isometric and eccentric quadriceps strength. Ipsilateral voluntary and stimulated forces increased in all groups. Changes in EMG activity paralleled those in voluntary force in each limb. No changes occurred in grip strength. The great contra- and ipsilateral strength gains after EMS training were most likely related to an additive effect of EMS and muscle lengthening.
This paper explores the feasibility of integrating energyefficiency program evaluation with the emerging need for the evaluationof programs from different "energy cultures" (demand response, renewableenergy, and climate change). The paper reviews key features andinformation needs of the energy cultures and critically reviews theopportunities and challenges associated with integrating these withenergy efficiency program evaluation. There is a need to integrate thedifferent policy arenas where energy efficiency, demand response, andclimate change programs are developed, and there are positive signs thatthis integration is starting to occur.

Tryptophan, a precursor of important molecules such as serotonin, melatonin and niacin, is an essential amino acid for dogs. In pigs, tryptophan supplementation has been shown to induce a significant increase in food intake. The aim of the present study was to assess whether long-term tryptophan supplementation increases voluntary food intake in dogs and to observe whether this was accompanied by a change in serum ghrelin. In the present study, sixteen adult Beagle dogs were used, with four male and four female dogs fed diets supplemented with tryptophan (1 g/dog per d) during 81 d (Trp) and four male and four female dogs that were not supplemented (control). A voluntary food intake test was performed during 5 d following the supplementation period. The Trp group tended to show a higher food intake during the voluntary food intake test (58.0 (SE 5.37) v. 77.5 (SE 3.65) g/kg metabolic weight per d; P = 0.074). No significant differences were found for serum ghrelin concentrations.

In paediatric oncology, research and treatments are often closely combined, which may compromise voluntary informed consent of parents. We identified two key scenarios in which voluntary informed consent for paediatric oncology studies is potentially compromised due to the intertwinement of research and care. The first scenario is inclusion by the treating paediatric oncologist, the second scenario concerns treatments confined to the research context. In this article we examine whether voluntary informed consent of parents for research is compromised in these two scenarios, and if so whether this is also morally problematic. For this, we employ the account of voluntary consent from Nelson and colleagues, who assert that voluntary consent requires substantial freedom from controlling influences. We argue that, in the absence of persuasion or manipulation, inclusion by the treating physician does not compromise voluntariness. However, it may function as a risk factor for controlling influence as it narrows the scope within which parents make decisions. Furthermore, physician appeal to reciprocity is not controlling as it constitutes persuasion. In addition, framing information is a form of informational manipulation and constitutes a controlling influence. In the second scenario, treatments confined to the research context qualify as controlling if the available options are restricted through manipulation of options. Although none of the influences is morally problematic in itself, a combination of influences may create morally problematic instances of involuntary informed consent. Therefore, safeguards should be implemented to establish an optimal environment for parents to provide voluntary informed consent in an integrated research-care context. © 2015 John Wiley & Sons Ltd.

Although focused on recently, ocean acidification is not the only effect of anthropogenic CO2 emissions on the ocean. Ocean warming will reduce dissolved oxygen concentrations and at the hypoxic limit for a given species this can pose challenges to marine life. The limit is traditionally reported simply as the static mass concentration property [O2]; here we treat it as a dynamic gas exchange problem for the animal analogous to gas exchange at the sea surface. The diffusive limit and its relationship to water velocity is critical for the earliest stages of marine life (eggs, embryos), but the effect is present for all animals at all stages of life. We calculate the external limiting O2 conditions for several representative metabolic rates and their relationship to flow of the bulk fluid under different environmental conditions. Ocean O2 concentrations decline by ≈ 14 μmol kg-1 for a 2 °C rise in temperature. At standard 1000 m depth conditions in the Pacific, flow over the surface would have to increase by ≈ 60% from 2.0 to 3.2 cm s-1 to compensate for this change. The functions derived allow new calculations of depth profiles of limiting O2 concentrations, as well as maximal diffusively sustainable metabolic oxygen consumption rates at various places around the world. Our treatment shows that there is a large variability in the global ocean in terms of facilitating aerobic life. This variability is greater than the variability of the oxygen concentration alone. It becomes clear that temperature and pressure dependencies of diffusion and partial pressure create a region typically around 1000 m depth where a maximal [O2] is needed to sustain a given metabolic rate. This zone of greatest physical constriction on the diffusive transport in the boundary layer is broadly consistent with the oxygen minimum zone, i.e., the zone of least oxygen concentration supply, resulting in a pronounced minimum of maximal diffusively sustainable metabolic oxygen consumption

During muscle fatigue, firing of small-diameter muscle afferents can decrease voluntary activation of the fatigued muscle. However, these afferents may have a more widespread effect on other muscles in the exercising limb. We examined if the firing of fatigue-sensitive afferents from elbow extensor muscles in the same arm reduces torque production and voluntary activation of elbow flexors. In nine subjects we examined voluntary activation of elbow flexors by measuring changes in superimposed twitches evoked by transcranial magnetic stimulation of the motor cortex during brief (2-3 s) maximal voluntary contractions (MVC). Inflation of a blood pressure cuff following a 2-min sustained MVC blocked blood flow to the fatigued muscle and maintained firing of small-diameter afferents. After a fatiguing elbow flexion contraction, maximal flexion torque was lower (26.0 ± 4.4% versus 67.9 ± 5.2% of initial maximal torque; means ± s.d.; P torque was also reduced (82.2 ± 4.9% versus 91.4 ± 2.3% of initial maximal torque; P = 0.007), superimposed twitches were larger (2.7 ± 0.7% versus 1.3 ± 0.2% ongoing MVC; P = 0.02) and voluntary activation lower (81.6 ± 8.2% versus 95.5 ± 6.9%; P = 0.04) with than without ischaemia. After a fatiguing contraction, voluntary drive to the fatigued muscles is reduced with continued input from small-diameter muscle afferents. Furthermore, fatigue of the elbow extensor muscles decreases voluntary drive to unfatigued elbow flexors of the same arm. Therefore, firing of small-diameter muscle afferents from one muscle can affect voluntary activation and hence torque generation of another muscle in the same limb.
Full Text Available Countries promoting renewable energies encounter a variety of phenomena that can challenge the implementation of further onshore wind energy development. Those challenges can be observed in many multi-level governance systems, as exhibited in the U.S., Germany, and Mexico, where various regulatory and institutional levels must agree on goals and responsibilities. This is a challenge, as both forms of governance (top-down and bottom-up dominated are present in wind energy planning and policy. (1 Political and market phenomena, (2 siting issues, (3 the green vs. green dilemma, and (4 social acceptance are selected challenges within the different levels of decision-making processes in wind energy implementation. (1 Political and financial factors can influence the development by implementing incentive- and market-based policies, command-and-control policies, and feed-in tariffs. However, success of these policy designs for renewable energies is based on different political environments, and their electricity markets nationally, regionally, or statewide. (2 Spatial limitations in planning are created based on limited land availability due to conflicts with other land uses such as aviation, nature reserves, residential areas, their respective buffers. (3 The "green vs. green" dilemma involves the incoherent relationship between policies promoting renewable energies with policies protection species and their environments, becoming a major point of concern during siting and operations of wind energy. (4 Lastly, while there is a general overall support for wind energy, social acceptance on a local level is influenced by institutional settings i.e. information availability, as well as public and stakeholder concerns. Involvement in decision-making as well as financial participation (e.g. community-ownership affects public participation and acceptance.

Full Text Available The present study was designed to investigate hemochromatosis patients' suitability as blood donors as well as their perceptions and experience with the current public donation system. Participants were gathered from a list of current hemochromatosis patients (n=120 and members of the Canadian Hemochromatosis Society (n=1000. Of the 1120 surveys mailed out to these groups, 801 surveys were returned completed. The sample respondents had a mean age of 57.44 years (SD=12.73; range 19 to 87 years, and 57% were men. It was found that 20% (160 of the respondents have donated blood since their diagnosis; however, only 12% of the respondents indicated that they use voluntary blood donation as a means of maintaining their iron levels. Forty per cent of the respondents indicated that they had been refused from voluntary donation. Despite the fact that in May 2001 the Canadian Blood Services, in collaboration with the Canadian Hemochromatosis Society, began a promotion campaign to encourage hemochromatosis patients to become voluntary blood donors, the present study found that 15% of the respondents reported having been refused from the voluntary blood donation service due to the diagnosis of hemochromatosis. With respect to quality of life, it was found that individuals who donate blood were generally healthier with respect to physical functioning and bodily pain, however, these findings may indicate that hemochromatosis patients who are healthier are better able to donate at public blood banks, rather than that voluntary blood donation has an effect on the donors' physical functioning over phlebotomy clinic users. These study findings suggest that although there may be other medical factors limiting individuals from donating, hemochromatosis patients are interested in being voluntary blood donors and this potential resource is currently under-used.

Over the past two decades, perfluorocarbon (PFC) droplets have been investigated for biomedical applications across a wide range of imaging modalities. More recently, interest has increased in "phase-change" PFC droplets (or "phase-change" contrast agents), which can convert from liquid to gas with an external energy input. In the field of ultrasound, phase-change droplets present an attractive alternative to traditional microbubble agents for many diagnostic and therapeutic applications. Despite the progress, phase-change PFC droplets remain far from clinical implementation due to a number of challenges. In this review, we survey our recent work to enhance the performance of phase-change agents for ultrasound through a variety of techniques in order to provide increased efficacy in therapeutic applications of ultrasound and enable previously unexplored applications in diagnostic and molecular imaging.

Full Text Available Depression symptoms following immune response to a challenge have been reported after the recovery from sickness. A RNA-Seq study of the dysregulation of the microglia transcriptome in a model of inflammation-associated depressive behavior was undertaken. The transcriptome of microglia from mice at day 7 after Bacille Calmette Guérin (BCG challenge was compared to that from unchallenged Control mice and to the transcriptome from peripheral macrophages from the same mice. Among the 562 and 3,851 genes differentially expressed between BCG-challenged and Control mice in microglia and macrophages respectively, 353 genes overlapped between these cells types. Among the most differentially expressed genes in the microglia, serum amyloid A3 (Saa3 and cell adhesion molecule 3 (Cadm3 were over-expressed and coiled-coil domain containing 162 (Ccdc162 and titin-cap (Tcap were under-expressed in BCG-challenged relative to Control. Many of the differentially expressed genes between BCG-challenged and Control mice were associated with neurological disorders encompassing depression symptoms. Across cell types, S100 calcium binding protein A9 (S100A9, interleukin 1 beta (Il1b and kynurenine 3-monooxygenase (Kmo were differentially expressed between challenged and control mice. Immune response, chemotaxis, and chemokine activity were among the functional categories enriched by the differentially expressed genes. Functional categories enriched among the 9,117 genes differentially expressed between cell types included leukocyte regulation and activation, chemokine and cytokine activities, MAP kinase activity, and apoptosis. More than 200 genes exhibited alternative splicing events between cell types including WNK lysine deficient protein kinase 1 (Wnk1 and microtubule-actin crosslinking factor 1(Macf1. Network visualization revealed the capability of microglia to exhibit transcriptome dysregulation in response to immune challenge still after resolution of sickness

Objective. Studies have shown that low frequency components of brain recordings provide information on voluntary hand movement directions. However, non-invasive techniques face more challenges compared to invasive techniques. Approach. This study presents a novel signal processing technique to extract features from non-invasive electroencephalography (EEG) recordings for classifying voluntary hand movement directions. The proposed technique comprises the regularized wavelet-common spatial pattern algorithm to extract the features, mutual information-based feature selection, and multi-class classification using the Fisher linear discriminant. EEG data from seven healthy human subjects were collected while they performed voluntary right hand center-out movement in four orthogonal directions. In this study, the movement direction dependent signal-to-noise ratio is used as a parameter to denote the effectiveness of each temporal frequency bin in the classification of movement directions. Main results. Significant (p EEG data was identified largely towards the end of movement at low frequencies (≤6 Hz) from the midline parietal and contralateral motor areas. Experimental results on single trial classification of the EEG data collected yielded an average accuracy of (80.24 ± 9.41)% in discriminating the four different directions using the proposed technique on features extracted from low frequency components. Significance. The proposed feature extraction strategy provides very high multi-class classification accuracies, and the results are proven to be more statistically significant than existing methods. The results obtained suggest the possibility of multi-directional movement classification from single-trial EEG recordings using the proposed technique in low frequency components.

Agonist-mediated reciprocal inhibition (RI) in distal skeletal muscles is an important neurophysiological phenomenon leading to improved movement coordination and efficiency. It has been shown to be reduced in aged and clinical populations, so the development of interventions augmenting RI is an important research goal. We examined the efficacy of using chronic passive muscle stretching to augment RI. The influence of 3 wk of plantarflexor stretching (4 × 30 s, two times/day) on RI of soleus and gastrocnemius initiated by tonic, voluntary dorsiflexion contractions [20% of maximum voluntary contraction (MVC)] was examined in 11 healthy men who performed stretch training and in nine nontraining controls. Hoffmann's reflexes (H-reflexes) were elicited by tibial nerve stimulation during both weak isometric (2% MVC) plantarflexions and dorsiflexion contractions at 20% MVC. Changes were examined at three joint angles, normalized to each subject's range of motion (ROM; plantarflexed = 10 ± 0°, neutral = -3.3 ± 2.9°, dorsiflexed = -16.5 ± 5.6°). No changes were detected in controls. A 20% increase in ROM in the stretch subjects was associated with a significant decrease in maximum H-reflex (H(max)): maximum evoked potential (M(max)), measured during 2% plantarflexion at the plantarflexed and neutral angles in soleus and at the plantarflexed angle in gastrocnemius (P dorsiflexion contract were also seen at each angle in soleus and at the dorsiflexed angle in gastrocnemius. However, a greater decrease in H(max):M(max) measured during voluntary dorsiflexion rather than during plantarflexion, which indicates a specific change in RI, was detected only at the dorsiflexed angle (-30.7 ± 9.4% and -35.8 ± 6.8% for soleus and gastrocnemius, respectively). These results demonstrate the efficacy of soleus-gastrocnemius stretch training in increasing agonist-mediated RI from tibialis anterior onto soleus-gastrocnemius in young, healthy individuals at dorsiflexed, but not

The UK, like the rest of the world, is confronting the impacts of climate change. Further changes are expected and they will have a profound effect on agriculture. Future crop production will take place against increasing CO2 levels and temperatures, decreasing water availability, and increasing frequency of extreme weather events. This review contributes to research on agricultural practices for climate change, but with a more regional perspective. The present study explores climate change impacts on UK agriculture, particularly food crop production, and how to mitigate and build resilience to climate change by adopting and/or changing soil management practices, including fertilisation and tillage systems, new crop adoption and variety choice. Some mitigation can be adopted in the shorter term, such as changes in crop type and reduction in fertiliser use, but in other cases the options will need greater investment and longer adaptation period. This is the case for new crop variety development and deployment, and possible changes to soil cultivations. Uncertainty of future weather conditions, particularly extreme weather, also affect decision-making for adoption of practices by farmers to ensure more stable and sustainable production. Even when there is real potential for climate change mitigation, it can sometimes be more difficult to accomplish with certainty on-farm. Better future climate projections and long-term investments will be required to create more resilient agricultural systems in the UK in the face of climate change challenges. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Full Text Available Semi-arid cereal systems face challenges worldwide that are driven by ongoing and projected climate change. These challenges include ensuring cropping system resilience and productivity under changing water and temperature regimes while reversing soil degradation, reducing crop susceptibility to pests, pathogens and weed competition, and exploiting genetic resources to develop cultivars with resilience to climate stresses and improved compatibility with cropping system innovations. Meeting these interdependent challenges requires transdisciplinary efforts that integrate knowledge across many scientific domains. The USDA-NIFA-funded coordinated agricultural project, “Regional Approaches to Climate Change for Pacific Northwest Agriculture” (REACCH, employed this transdisciplinary approach to address climate change and sustainability challenges for rain-fed cereal-based systems in the semi-arid intermountain Pacific Northwest. To engage with and contribute to similar efforts globally, REACCH sponsored a workshop “Transitioning Cereal Systems to Adapt to Climate Change” (TCSACC in November 2015. Participants from 17 countries and five continents with expertise in agronomy, crop physiology, crop modeling, crop protection, breeding and genetics, sociology and economics shared their perspectives, successes, and challenges to achieving transdisciplinary research integration for semi-arid cereal systems under changing climates. Conference goals were to: (1 strengthen the global network of researchers addressing climate change effects on semi-arid cereal-based systems, (2 share the approaches to achieving transdisciplinary collaboration to advance climate change resilience in cereal systems, and (3 identify the elements of a collaborative research agenda that are needed to advance global food security in the twenty-first century. This paper distills the conference themes and summarizes the calls to action that were discussed: Establish coordinated

Spectral power (SP) of EEG alpha and beta-2 frequencies in different cortical areas has been used for neurofeedback training to control a graphic interface in different scenarios. The results show that frequency range and brain cortical areas are associated with high or low efficiency of voluntary control. Overall, EEG phenomena observed in the course of training are largely general changes involving extensive brain areas and frequency bands. Finally, we have demonstrated EEG patterns that dynamically switch with a specific feature in different tasks within one training, after a relatively short period of training.
This article examines the evidence for the empirical argument that there is a slippery slope between the legalization of voluntary and non-voluntary euthanasia. The main source of evidence in relation to this argument comes from the Netherlands. The argument is only effective against legalization if it is legalization which causes the slippery slope. Moreover, it is only effective if it is used comparatively-to show that the slope is more slippery in jurisdictions which have legalized voluntary euthanasia than it is in jurisdictions which have not done so. Both of these elements are examined comparatively.

Climate change poses a major threat to public health. Strategies that address climate change have considerable potential to benefit health and decrease health inequities, yet public health engagement at the intersection of public health, equity, and climate change has been limited. This research seeks to understand the barriers to and opportunities for advancing work at this nexus. We conducted semi-structured in-depth interviews (N = 113) with public health and climate change professionals and thematic analysis. Barriers to public health engagement in addressing climate change include individual perceptions that climate change is not urgent or solvable and insufficient understanding of climate change's health impacts and programmatic connections. Institutional barriers include a lack of public health capacity, authority, and leadership; a narrow framework for public health practice that limits work on the root causes of climate change and health; and compartmentalization within and across sectors. Opportunities include integrating climate change into current public health practice; providing inter-sectoral support for climate solutions with health co-benefits; and using a health frame to engage and mobilize communities. Efforts to increase public health sector engagement should focus on education and communications, building leadership and funding, and increasing work on the shared root causes of climate change and health inequities.

Full Text Available As universities invest in the development of e-learning resources, e-learning sustainability has come under consideration. This has largely focused on the challenges and facilitators of organisational and technological sustainability and scalability, and professional development. Little research has examined the experience of a teacher dealing with e-learning sustainability when taking over a course with an e-learning resource and associated assessment. This research focuses on a teacher who was inexperienced with e-learning technology, yet took over a blended unit of study with an e-learning resource that accounted for one-fifth of the subject assessment and was directed towards academic skills development relevant to the degree program. Taking a longitudinal approach, this research examines the challenges faced by the new teacher and the way she changed the e-learning resource and its implementation over two years. A focus of the research is the way the teacher's reflections on the challenges and changes provided an opportunity and stimulus for change in her e-learning beliefs and practices. This research has implications for the way universities support teachers taking over another teacher's e-learning resource, the need for explicit documentation of underpinning beliefs and structured handover, the benefit of teamwork in developing e-learning resources, and provision of on-going support.

There is very little information regarding blood changes during the challenge of phospholipase D (PLD) in goats. Therefore, this experiment was conducted to study the changes in blood after the challenge with Corynebacterium pseudotuberculosis and its exotoxin, PLD to fill in the gap of caseous lymphadenitis (CLA) research. Twenty-six crossbred Boer goats aged 12-14 months were divided into 3 groups; the first group n=6 was inoculated with 1 ml phosphate buffered solution s.c. as the control. The second group n=10 was inoculated with C. pseudotuberculosis 1 × 10(9) cfu s.c. The third group n=10 was intravenous injected with PLD 1 ml/20 kg body weight. Serial blood collections were done at 1 h, 3 h, 5 h, 8 h, and 12 h then every 24 h post-inoculation for the first 30 days of the experiment. Subsequently, the blood collection continued twice a week till the end of the experiment (90 days post-challenge). Both C. pseudotuberculosis and PLD treated groups showed significant changes (pleukogram, and the blood chemistry.

Voluntary drinking is one of the major determiners of rehydration, especially as regards exercise or workout in the heat. The present study undertakes to search for the effect of voluntary intake of water with different temperatures on fluid balance in Taekwondo athletes. Six young healthy male Taekwondo athletes were dehydrated by moderate exercise in a chamber with ambient temperature at 38-40°C and relative humidity between 20-30%. On four separate days they were allowed to drink ad libitum plane water with the four temperatures of 5, 16, 26, and 58°C, after dehydration. The volume of voluntary drinking and weight change was measured; then the primary percentage of dehydration, sweat loss, fluid deficit and involuntary dehydration were calculated. Voluntary drinking of water proved to be statistically different in the presented temperatures. Water at 16°C involved the greatest intake, while fluid deficit and involuntary dehydration were the lowest. Intake of water in the 5°C trial significantly correlated with the subject's plasma osmolality change after dehydration, yet it showed no significant correlation with weight loss. In conclusion, by way of achieving more voluntary intake of water and better fluid state, recommending cool water (~16°C) for athletes is in order. Unlike the publicly held view, drinking cold water (~5°C) does not improve voluntary drinking and hydration status. Key pointsFor athletes dehydrated in hot environments, maximum voluntary drinking and best hydration state occurs with 16°C water.Provision of fluid needs and thermal needs could be balanced using 16°C water.Drinking 16°C water (nearly the temperature of cool tap water) could be recommended for exercise in the heat.

Full Text Available In Christianity, there is an ideology of motherhood that pervades scripture, ritual, and doctrine, yet there is an academic silence that means relatively little space has been given to motherhood and mothering, and even less to voluntary childlessness, from a faith perspective. By drawing on qualitative in-depth interviews with Christian women living in Britain, narrating their experiences of motherhood and voluntary childlessness, I suggest there are also lived maternal silences encountered by women in contemporary Christianity. There is a maternal expectation produced through church teaching, liturgy and culture that constructs women as ‘maternal bodies’ (Gatrell 2008; this silences and marginalises women from articulating their complex relationship with religion, motherhood, and childlessness in ways that challenge their spiritual development. However, this article also introduces the everyday and intentional tactics women employ to disrupt the maternal expectation, and hereby interrupt the maternal silence.

Climate change threatens water, sanitation and hygiene (WaSH) facilities and services, as these are intimately linked to the water cycle and are vulnerable to changes in the quantity and quality of available water resources. Floods and droughts, which pollute and reduce water delivery respectively, have now become a perennial issue to deal with in the northern regions of Ghana. This study aimed to assess the degree to which climate change adaptation measures are mainstreamed into the water, sanitation and hygiene (WaSH) development planning process in Ghana. Stakeholders from government and non-government agencies were interviewed to gain perspectives on the threat of climate change, the inclusion of climate change in WaSH planning and the barriers preventing mainstreaming. Despite awareness of climate change, adaptation measures have not been considered, and the immediate WaSH needs remain the priority. Overall, stakeholders felt the adaptive capacity of the Municipality was low and that mainstreaming has not yet occurred. Despite the lack of progress, there are great opportunities for mainstreaming climate change adaptation into planning through increasing awareness and capacity, legislative and institutional changes and the development of participatory systems to provide early warning systems and disaster risk analyses that will inform future planning.

Full Text Available This introduction into the special issue of European Countryside describes the need to move from knowledge to action and from simplification to complexification in contemporary discourses about demographic change. While the first movement arguably refers to the contributions of this issue the latter is a plea towards more specification and differentiation when investigating and assessing phenomena of demographic change.

Full Text Available Along with the growing scientific and political concern on global warming, the relationship of climate and migration is framed as cause and consequence. Alarmist numbers of mass migration and related conflicts currently represent the main scientific narratives merging the issue of migration and climate change. This paper takes a different and explorative perspective: it suggests that scientific discourses on migration and climate change should be reframed by taking into consideration the diverse ‘knowledges’ offered by migrants. Employing an experimentalist approach, we aim at filling this gap in research and introduce an empirical perspective on climate framings among Italian and Chinese citizens in the local context of the city of Hamburg (Germany. Qualitatively analysing semi-structured interviews, the paper conveys an in-depth analysis of how Italian and Chinese migrants frame climate change and, furthermore, explores philosophical backgrounds informing them. We start with a theoretical and methodological outline on undertaking research with migrants and then turn to an empirical analysis in which we examine and discuss four prevailing categories found in the course of our investigation. The final section summarises the results and reflects upon the methodological and theoretical approach applied which refers to the relevance of migrants as active actors in local adaptation and mitigation processes of the hosting country.

Fifteen years ago, Bill Gates was a college dropout working for a four-member, fledgling company in New Mexico. Today, he is the richest man in America and the head of perhaps the most powerful company in recent corporate history. Ten years ago, managed health care was merely a concept discussed in academic and industry observer circles. Now it is a norm in almost every health-care organization nationally. Five years ago, health-care professionals in every discipline believed the maxim that, ¿as long as people get sick, health-care professionals will have jobs.¿ In 1995, health-care executives have alternately referred to the widescale process of laying off employees as reengineering, rightsizing, downsizing, or RIF (reduction in force). With this massive amount of change, both societally and professionally, health-care managers have been contending with the change management process. Although a breadth of concepts borrowed from other industries and a plethora of conceptual practicums have entered the health-care educational realm, a straightforward, immediately useful approach to managing change is probably more beneficial, as the need to manage change quickly and effectively becomes the paramount criterion for health-care management success in the second half of this decade of change. In this article we will explore the four areas where mistakes are made most frequently by leaders in the change process, and we will provide specific strategies to not only avoid these mistakes but moreover reduce resistance to change, activate positive action, and ultimately improve performance through optimum staff contribution. The four critical areas we will explore are the reasons for resistance to change, the management of the proactive phase of change, creating staff interdependence, and key leadership roles for change management.

Full Text Available The present article discusses the relevance of theorizing educational practice and the challenge of breaking with the belief that theory and practice are impervious and separate things. It stresses the continuous upgrading of the teachers whose practice of study and collective research will lead them to exploit their own creative capacity through the systematization of their fields of experience in the school environment. It also highlights self-perception increased by facing linguistic, emotional, ideological, economic and political meanings which impress a pedagogical significance on his/her practice.

Hospitals in the Netherlands are now operating in a rapidly changing environment. Most changes directly result from government's policy to achieve effective cost containment in health care. Some of them basically affect the existence and functioning of hospitals. These changing environmental conditions inspire hospitals to undertake innovative activities to protect or even strengthen their position. This will be illustrated below by a case in which a small acute hospital attempted to establish a close relationship with primary health care in order to protect its position. Our focus will be upon this innovative initiative and upon some management problems that must then be resolved.

This paper discusses the implementation of considerations resulting from a study investigating the cost change experienced by historical NASA science missions. The study investigated historical milestone and monthly status report documentation followed by interviews with key project personnel. The reasons for cost change were binned as being external to NASA, external to the project and internal to the project relative to the project's planning and execution. Based on the results of the binning process and the synthesis of project meetings and interviews, ten considerations were made with the objective to decrease the potential for cost change in future missions. Although no one magic bullet consideration was discovered, the considerations taken as a whole should help reduce cost and schedule change in future NASA missions.
The concept of adaptation to climate change has gained strong momentum worldwide since its emergence in the early 1990s, particularly in recent years. Regardless of the outcome of ongoing international climate negotiations, adaptation to climate change is particularly important for poor communities and those vulnerable to various climate hazards, such as flooding, drought, landslides and cyclones/hurricanes. Owing to the unavoidably local nature of adaptation, one must consider a series of ac...

An illuminating method for evaluating the moral status of a practice is to follow the implications of the practice to its logical conclusion. The argument for compassion is one of the central arguments in favour of voluntary active euthanasia. This argument applies perhaps even more forcefully in relation to incompetent patients. If active voluntary euthanasia is legalised, arguments based on compassion and equality will be directed towards legalising active non-voluntary euthanasia in order to make accelerated termination of death available also to the incompetent. The removal of discrimination against the incompetent has the potential to become as potent a catch-cry as the right to die. However, the legalisation of non-voluntary euthanasia is undesirable. A review of the relevant authorities reveals that there is no coherent and workable "best interests" test which can be invoked to decide whether an incompetent patient is better off dead. This provides a strong reason for not stepping onto the slippery path of permitting active voluntary euthanasia.

BACKGROUND Dietary changes among Latino immigrants are often attributed to acculturation. Acculturation-diet research typically assumes that migration to the US is necessary for negative dietary changes to occur in Latino immigrants’ diets. OBJECTIVE The goal of this article is to demonstrate that extant acculturation research is not adequate in capturing changes in Latino immigrants’ diets. This is due to the role of globalization and transnational processes in modernizing their diets in Latin America. DESIGN Utilizing an interactionist cultural studies approach, this exploratory situational analysis based on 27 in-depth interviews with Latino immigrants, nutrition reports, and transnational food companies’ websites, examines how Latino immigrants were already engaging in negative dietary practices in their former country. RESULTS Latino immigrants who resided in urban areas in their former countries and migrated to the US on or after 2000 were fully engaged in negative dietary practices prior to migration. Such practices included consuming food outside of the home and integrating processed food into their cooking. Their dietary practices were also informed by nutrition discourses. The modernization of food production and consumption and the transnational transmission of nutrition are transnational processes changing Latino immigrants’ diets prior to migration. CONCLUSION Researchers should approach the study of dietary change among Latino immigrants in the US through a transnational perspective in order to avoid overlooking potential confounders such as current food insecurity, new socioeconomic positions as undocumented, low-income persons, and increased hours worked outside of the home.

Full Text Available Global climate change increases heat loads in urban areas causing health and productivity risks for millions of people. Inhabitants in tropical and subtropical urban areas are at especial risk due to high population density, already high temperatures, and temperature increases due to climate change. Air conditioning is growing rapidly, especially in South and South-East Asia due to income growth and the need to protect from high heat exposures. Studies have linked increased total hourly electricity use to outdoor temperatures and humidity; modeled future predictions when facing additional heat due to climate change, related air conditioning with increased street level heat and estimated future air conditioning use in major urban areas. However, global and localized studies linking climate variables with air conditioning alone are lacking. More research and detailed data is needed looking at the effects of increasing air conditioning use, electricity consumption, climate change and interactions with the urban heat island effect. Climate change mitigation, for example using renewable energy sources, particularly photovoltaic electricity generation, to power air conditioning, and other sustainable methods to reduce heat exposure are needed to make future urban areas more climate resilient.

Dietary changes among Latino immigrants are often attributed to acculturation. Acculturation-diet research typically assumes that migration to the US is necessary for negative dietary changes to occur in Latino immigrants' diets. The goal of this article is to demonstrate that extant acculturation research is not adequate in capturing changes in Latino immigrants' diets. This is due to the role of globalization and transnational processes in modernizing their diets in Latin America.

Full Text Available Over the past two decades, perfluorocarbon (PFC droplets have been investigated for biomedical applications across a wide range of imaging modalities. More recently, interest has increased in “phase-change” PFC droplets (or “phase-change” contrast agents, which can convert from liquid to gas with an external energy input. In the field of ultrasound, phase-change droplets present an attractive alternative to traditional microbubble agents for many diagnostic and therapeutic applications. Despite the progress, phase-change PFC droplets remain far from clinical implementation due to a number of challenges. In this review, we survey our recent work to enhance the performance of phase-change agents for ultrasound through a variety of techniques in order to provide increased efficacy in therapeutic applications of ultrasound and enable previously unexplored applications in diagnostic and molecular imaging.
Full Text Available Higher Education has a vital role in developing an internationally competitive economy, a more affluent society and a sturdy democracy. The newly released National Plan for Higher Education in South Africa should recognise the current social and economic status in the country to realign its mission, and to reconsider the location and target audience of the various institutions in the country, to optimally serve the educational needs of the communities. The proposals in the National Plan, however, attempts to attain in a few years what other stabilised countries took years. That poses major challenges to education management. The aim of this paper is to evaluate some aspects of the managerial skills in the national education authorities. By analysing the National Plan, and testing the views of a number of teaching staff, the conclusion is that there are serious doubts regarding the management acumen in the educational leadership and that various important aspects are left out in the Plan.
Full Text Available A large part of the economic literature is unanimous in believing technological progress and openness to foreign trade are key variables to trigger the processes of stable and persistent economic growth. An in-depth analysis of these factors, thus, becomes necessary both to meet the challenges of the international market, and to strengthen the European integration process. This paper aims to provide an empirical analysis of the interaction between foreign trade and technological progress by performing a multidimensional scaling. This technique is used to produce a graphical representation of the 27 EU member states, in accordance to the degree of similarity or dissimilarity between them. The indicators used, and the indexes calculated, reflect the different degree of internationalization of each countrys economy, the regulation of trade flows, investment in specific RD and technological progress.

Freshwater resources of India are getting fast degraded and depleted from the changing climate and pressure of fast rising population. Changing intensity and seasonality of rainfall affect quantity and quality of water. Most of the rivers are polluted far above safety limits from the untreated domestic, industrial and agricultural effluents. Changes in the intensity, frequency and tracks of storms salinate coastal aquifers. Aquifers are also under the threat from rising sea level. Groundwater in urban limits and industrial zones are far beyond safety limits. Large-scale destruction of wetlands for industries and residential complexes has affected the quality of surface and groundwater resources in most parts of India. Measures to maintain food security and the new developments schemes such as river linking will further deteriorate the water resources. Falling water availability leads to serious health issues and various socio-economic issues. India needs urgent and appropriate adaptation strategies in the water sector.

The municipalities of the Czech Republic have been facing negative impacts of changing climate in the past decades - especially floods (1997, 2002, 2010, 2013), droughts and heat waves (2013, 2015), claiming lives, material damages and economic losses up to several % of GDP. Reflecting these events, climate change adaptation should represent major issue in strategical planning on all administrative levels, which is actually not fully met nowadays. Sectoral National Adaptation Strategy (NAS) was approved by the Government of the Czech Republic in autumn 2015 and the implementation action plan is currently being approved. Adaptation strategies on lower administrative level (adaptation strategies of individual municipalities) are, however, still quite rare. In this contribution, we analyse barriers and challenges for: (i) the development of climate change adaptation strategies on administrative level of individual municipalities in the Northwest region, Czech Republic; and (ii) implementation of adaptation measures into the decision-making processes. Based on participatory seminars with key stakeholders organised in pilot municipalities, it was shown that municipalities are (at least partly) able to cope with existing risks such as floods, but are not well-prepared for expected regionally "new" risks such as long lasting heat waves, insufficient water retention and flash floods. Linking the goals of adaptation strategy with urban planning seems to be challenging task but also potentially powerfull tool to implement specific adaptation measures. It emerged, that complicated ownership relations often cause obstacles for implementation of adaptation measures, highlighting the potential of stimulation and motivation tools from the side of the municipality. On the other hand, it was also shown that despite experiencing its negative impacts, climate change is often neglected or percepted as a marginal issue by some municipalities and developing adaptation strategy is

Abstract Research gaps in understanding flood changes at the catchment scale caused by changes in forest management, agricultural practices, artificial drainage, and terracing are identified. Potential strategies in addressing these gaps are proposed, such as complex systems approaches to link processes across time scales, long‐term experiments on physical‐chemical‐biological process interactions, and a focus on connectivity and patterns across spatial scales. It is suggested that these strategies will stimulate new research that coherently addresses the issues across hydrology, soil and agricultural sciences, forest engineering, forest ecology, and geomorphology.

The Los Alamos National Laboratory (LANL) has been adapting to climate change related impacts that have been occurring on decadal time scales. The region where LANL is located has been subject to a cascade of climate related impacts: drought, devastating wildfires, and historic flooding events. Instead of buckling under the pressure, LANL and the surrounding communities have integrated climate change mitigation strategies into their daily operations and long-term plans by increasing coordination and communication between the Federal, State, and local agencies in the region, identifying and aggressively managing forested areas in need of near-term attention, addressing flood control and retention issues, and more.

Recent surveys by the Vietnamese Ministry of Health suggest that 60% of married women desire no more children. Yet only 2% of currently married women and less than 1/2 of 1% of their partners use sterilization. Underscoring the high unmet need for effective family planning, over 1 million abortions (legal in Vietnam for the past 20 years) are performed annually. This rate corresponds to 1 abortion for every live birth. The Ministry of Health has recently welcomed a variety of organizations, including AVSC, whose assistance can help expand the country's family planning programs. Sorely lacking in supplies, equipment, and trained personnel, Vietnam has merited priority status--2nd only to China and India--from the UNFPA, which has committed $36 million over the next 4 years. Other organizations currently working in Vietnam include the Population Council, the Population Crisis Committee, and the International Planned Parenthood Federation. Despite enormous casualties during the war years, and a decrease since the 1970s in average family size from 6 to 4 children, the population of Vietnam has continued to grow rapidly, far outpacing economic growth. Currently 67 million, the population is expected to reach 80 million by the year 2000. The average Vietnamese annual income is only $195, among the lowest in the world. Doi moi, the process of economic reform begun in 1986, coupled with new government incentives for families who have no more than 2 children, is changing the face of family planning in Vietnam. Newly opened pharmacies sell imported birth control pills and condoms (to those who can afford them), while government hospitals and health clinics provide mainly IUDs, in addition to limited supplies of pills and condoms. Throughout the country, some 8000 community-level health centers are staffed by nurse-midwives trained in family planning. Voluntary sterilization is available at the district, provincial, and national hospitals. All married women may obtain family

Full Text Available Abstract Backgound Sulphadoxine/sulphalene-pyrimethamine (SP was adopted in Kenya as first line therapeutic for uncomplicated malaria in 1998. By the second half of 2003, there was convincing evidence that SP was failing and had to be replaced. Despite several descriptive investigations of policy change and implementation when countries moved from chloroquine to SP, the different constraints of moving to artemisinin-based combination therapy (ACT in Africa are less well documented. Methods A narrative description of the process of anti-malarial drug policy change, financing and implementation in Kenya is assembled from discussions with stakeholders, reports, newspaper articles, minutes of meetings and email correspondence between actors in the policy change process. The narrative has been structured to capture the timing of events, the difficulties and hurdles faced and the resolutions reached to the final implementation of a new treatment policy. Results Following a recognition that SP was failing there was a rapid technical appraisal of available data and replacement options resulting in a decision to adopt artemether-lumefantrine (AL as the recommended first-line therapy in Kenya, announced in April 2004. Funding requirements were approved by the Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM and over 60 million US$ were agreed in principle in July 2004 to procure AL and implement the policy change. AL arrived in Kenya in May 2006, distribution to health facilities began in July 2006 coincidental with cascade in-service training in the revised national guidelines. Both training and drug distribution were almost complete by the end of 2006. The article examines why it took over 32 months from announcing a drug policy change to completing early implementation. Reasons included: lack of clarity on sustainable financing of an expensive therapeutic for a common disease, a delay in release of funding, a lack of comparative efficacy data

Although many studies have shown that high temperatures are associated with an increased risk of mortality and morbidity, there has been little research on managing the process of planned adaptation to alleviate the health effects of heat events and climate change. In particular, economic evaluation of public health adaptation strategies has been largely absent from both the scientific literature and public policy discussion. We examined how public health organizations should implement adaptation strategies and, second, how to improve the evidence base required to make an economic case for policies that will protect the public's health from heat events and climate change. Public health adaptation strategies to cope with heat events and climate change fall into two categories: reducing the heat exposure and managing the health risks. Strategies require a range of actions, including timely public health and medical advice, improvements to housing and urban planning, early warning systems, and assurance that health care and social systems are ready to act. Some of these actions are costly, and given scarce financial resources the implementation should be based on the cost-effectiveness analysis. Therefore, research is required not only on the temperature-related health costs, but also on the costs and benefits of adaptation options. The scientific community must ensure that the health co-benefits of climate change policies are recognized, understood, and quantified. The integration of climate change adaptation into current public health practice is needed to ensure the adaptation strategies increase future resilience. The economic evaluation of temperature-related health costs and public health adaptation strategies are particularly important for policy decisions.

The health status of Aboriginal and Torres Strait Islander peoples continues to be significantly poorer than Australia's general population. Clearly there is a need for change, hence the renewed interest in transitioning to a community control model for health services as a health intervention. Yet this requires a significant change management process, which is a process developed using Western business philosophies, and may not be applicable for community-controlled services that need to operate within the Aboriginal cultural domain. This paper examines the literature on organisational change management processes, and features of Aboriginal community-controlled health organisations and Aboriginal management styles. It identifies challenges and synergies that can be used to inform more effective transition processes to a community-control model for health services. The findings also highlight the need for a fundamental systems change approach to achieve such major reform agendas through the creation of a "collective responsibility" to achieve the vision for change, utilising participatory change management processes both internally and externally.

To assess whether invasive and non-invasive blood pressure (BP) monitoring allows the identification of patients who have responded to a fluid challenge, i.e., who have increased their cardiac output (CO). Patients with signs of circulatory failure were prospectively included. Before and after a fluid challenge, CO and the mean of four intra-arterial and oscillometric brachial cuff BP measurements were collected. Fluid responsiveness was defined by an increase in CO ≥10 or ≥15% in case of regular rhythm or arrhythmia, respectively. In 130 patients, the correlation between a fluid-induced increase in pulse pressure (Δ500mlPP) and fluid-induced increase in CO was weak and was similar for invasive and non-invasive measurements of BP: r² = 0.31 and r² = 0.29, respectively (both p invasive Δ500mlPP was associated with an area under the receiver-operating curve (AUC) of 0.82 (0.74-0.88), similar (p = 0.80) to that of non-invasive Δ500mlPP [AUC of 0.81 (0.73-0.87)]. Outside large gray zones of inconclusive values (5-23% for invasive Δ500mlPP and 4-35% for non-invasive Δ500mlPP, involving 35 and 48% of patients, respectively), the detection of responsiveness or unresponsiveness to fluid was reliable. Cardiac arrhythmia did not impair the performance of invasive or non-invasive Δ500mlPP. Other BP-derived indices did not outperform Δ500mlPP. As evidenced by large gray zones, BP-derived indices poorly reflected fluid responsiveness. However, in our deeply sedated population, a high increase in invasive pulse pressure (>23%) or even in non-invasive pulse pressure (>35%) reliably detected a response to fluid. In the absence of a marked increase in pulse pressure (<4-5%), a response to fluid was unlikely.
The Voluntary Reporting of Greenhouse Gases Program, required by Section 1605(b) of the Energy Policy Act of 1992, records the results of voluntary measures to reduce, avoid, or sequester greenhouse gas emissions. In 1998, 156 US companies and other organizations reported to the Energy information Administration that, during 1997, they had achieved greenhouse gas emission reductions and carbon sequestration equivalent to 166 million tons of carbon dioxide, or about 2.5% of total US emissions for the year. For the 1,229 emission reduction projects reported, reductions usually were measured by comparing an estimate of actual emissions with an estimate of what emissions would have been had the project not been implemented.

This paper aims to develop a complex articulation of the civic meaningfulness of voluntary work that clarifies its political importance as a countervailing narrative pointing beyond dominant neoliberal and consumptive articulations of a good life. To start with, it sketches a hermeneutic perspective on civic meaningfulness based on the work of Paul Ricoeur. Subsequently, it introduces the ideas of 'ethical complexity', 'epistemological complexity' and 'diapoiesis', building on insights from critical complexity thinking and relational biology. It argues that these notions can provide a bridge between hermeneutic perspectives on meaning and values, on the one hand, and questions of meaning and values on the level of scientific and technological developments and within professional organizations, on the other. Thus a broader, more complex picture emerges of the civic meaningfulness of voluntary work in our times.

In the last 30 years, it has changed the prevalence an etiology of valvular heart diseases. They have diminished the rheumatic valvular diseases and have increased the degenerative etiology in elderly people. Globally they continue to be a major pathology in the Departments of Cardiology. The diagnosis has changed and echocardiography/doppler has turned into the basic test for the diagnosis and follow-up of these patients. This best knowledge of the evolution of the different pathologies has allowed the understanding of the more precise timing for surgical treatment, without awaiting the appearance of advanced symptomatology. The percutaneous technologies for the treatment are appearing as an alternative to the cardiac surgery for the patients with high rates of comorbidity and mortality.

Since the development of the first cytotoxic agents, synthetic organic chemistry has advanced enormously. The synthetic and medicinal chemists of today are at the centre of drug development and are involved in most, if not all, processes of drug discovery. Recent decreases in government funding and reformed educational policies could, however, seriously impact on drug discovery initiatives worldwide. Not only could these changes result in fewer scientific breakthroughs, but they could also negatively affect the training of our next generation of medicinal chemists.
Full Text Available The paper aims to analyze the extent of Ecosystem Service (ESS based Adaptation (EbA to climate change in the policy-making process of Bangladesh. The paper is based on a three stage hybrid policy-making cycle: (i agenda setting; (ii policy formulation; and (iii policy implementation stage, where the contributions of EbA can horizontally (on the ground or vertically (strategic stage be mainstreamed and integrated. A total of nine national and sectoral development and climate change policies, and 329 climate change adaptation projects are examined belonging to different policy-making stages. The major findings include that the role of ESS is marginally considered as an adaptation component in most of the reviewed policies, especially at the top strategic level (vertical mainstreaming. However, at the policy formulation and implementation stage (horizontal mainstreaming, they are largely ignored and priority is given to structural adaptation policies and projects, e.g., large scale concrete dams and embankments. For example, ESS’s roles to adapt sectors such as urban planning, biodiversity management and disaster risk reduction are left unchecked, and the implementation stage receives overwhelming priorities and investments to undertake hard adaptation measures such that only 38 projects are related to EbA. The paper argues that: (i dominant structural adaptation ideologies; (ii the expert and bureaucracy dependent policy making process; and (iii the lack of adaptive and integration capacities at institutional level are considerably offsetting the EbA mainstreaming process that need to be adequately addressed for climate change adaptation.

The work of health care reform and revolution requires leadership competencies that integrate the digital realities of time, space, and media. Leadership skills and behaviors of command, control, and directing from predigital times are no longer effective, given the impacts of the digital changes. Developing leadership competence in evidence-driven processes, facilitation, collaborative teamwork, and instilling a sense of urgency is the work of today's executive leaders. Ten competencies necessary for contemporary executive leadership are presented in this article.
Full Text Available Current society has to deal with major challenges related to our constantly increasing population of older adults. Since motor performance generally deteriorates at older age, research investigating the effects of different types of training on motor improvement is particularly important. Here, we tested the effects of contextual interference (CI while learning a bimanual coordination task in both young and older subjects. Both age groups acquired a low and high complexity task variant following either a blocked or random practice schedule. Typical CI effects, i.e. better overall performance during acquisition but detrimental effects during retention for the blocked compared with the random groups, were found for the low complexity task variant in both age groups. With respect to the high complexity task variant, no retention differences between both practice schedules were found. However, following random practice, better skill persistence (i.e. from end of acquisition to retention over a one week time interval was observed for both task complexity variants and in both age groups. The current study provides clear evidence that the effects of different practice schedules on learning a complex bimanual task are not modulated by age.

Postural stability may be compromised in patients who have sustained a traumatic brain injury (TBI). The purpose of the present study was to examine dynamic stability during gait by measuring spatial and temporal variability of foot placement, and to determine the effect of increased difficulty of the walking task on gait variability in patients with TBI. It was hypothesized that patients with TBI will show increased variability in step time, step length, and step width in comparison to healthy controls and that such differences would be accentuated by increased task difficulty. Participants (patients: n=20, controls: n=20) were asked to walk across a pressure sensitive mat at their preferred pace (PW), as fast as possible (FW), and with their eyes closed (EC). In accordance with the hypotheses, patients had significantly greater variability in step time and step length in comparison to healthy controls, and when the complexity of the gait task increased (FW and EC tasks). Although step width variability showed no significant difference between the groups, both control and patient groups had increased step width variability in the EC task. It is proposed that such increases in variability reflect greater challenges to maintaining dynamic stability during gait among individuals with TBI and when performing more difficult tasks.

Previous research suggests that the use of valid symbolic cues is sufficient to elicit voluntary shifts of attention. The present study interpreted this previous research within a broader theoretical context which contends that observers will voluntarily use symbolic cues to orient their attention in space when the temporal costs of using the cues are perceived to be less than the temporal costs of searching without the aid of the cues. In this view, previous research has not addressed the sufficiency of valid symbolic cues, because the temporal cost of using the cues is usually incurred before the target display appears. To address this concern, 70%-valid spatial word cues were presented simultaneously with a search display. In addition, other research suggests that opposing cue-dependent and cue-independent spatial biases may operate in these studies and alter standard measures of orienting. After identifying and controlling these opposing spatial biases, the results of two experiments showed that the word cues did not elicit voluntary shifts of attention when the search task was relatively easy but did when the search task was relatively difficult. Moreover, the findings also showed that voluntary use of the word cues changed over the course of the experiment when the task was difficult, presumably because the temporal cost of searching without the cue lessened as the task got easier with practice. Altogether, the present findings suggested that the factors underlying voluntary control are multifaceted and contextual, and that spatial validity alone is not sufficient to elicit voluntary shifts of attention.

Many studies have shown that Parkinson's disease (PD) affects not only the ability to generate voluntary saccades but also the ability to suppress reflexive saccades (hyper-reflexivity). To further investigate these apparently contradictory effects of PD on the saccade system we adapted a well-known dual-task paradigm (Deubel, 2008) to measure saccades with and without a peripheral discrimination task. Previously we reported that the concurrent performance of a perceptual discrimination task abnormally reduced the latencies of reflexive saccades in PD. Here we report the effects of the concurrent discrimination task on the generation of voluntary saccades in a PD and a control group. As expected, when saccades were performed without the discrimination task the PD group made voluntary saccades with longer latencies and smaller gain than the control group. The concurrent performance of the perceptual discrimination task facilitated the initiation of voluntary saccades in both groups, but, surprisingly, this facilitatory effect was stronger in the PD group than in the control group. In addition, in the PD group voluntary saccades were abnormally facilitated by the peripheral symbol-changes that occur during saccade planning in this paradigm. The results of this study may help to clarify apparently contradictory oculomotor abnormalities observed in PD. © 2012 Federation of European Neuroscience Societies and Blackwell Publishing Ltd.
Full Text Available A longer growing season and higher accumulated effective temperature sum (ETS will improve crop production potential in Finland. The production potential of new or at present underutilised crops (e.g. maize (Zea mays L., oilseed rape (Brassica napus L., lucerne (Medicago sativa L. will improve and it will be possible to grow more productive varieties of the currently grown crops (spring wheat (Triticum aestivum L., barley (Hordeum vulgare L., oats (Avena sativa L.. Also cultivation of autumn sown crops could increase if winters become milder and shorter, promoting overwintering success. Climatic conditions may on the other hand become restrictive in many ways. For example, early season droughts could intensify because of higher temperatures and consequent higher evaporation rates. Current low winter temperatures and short growing season help restrict the development and spread of pests and pathogens, but this could change in the future. Longer growing seasons, warmer autumns and milder winters may initiate new problems with higher occurrences of weeds, pests and pathogens, including new types of viruses and virus vectors. Anoxia of overwintering crops caused by ice encasement, and physical damage caused by freezing and melting of water over the fields may also increase. In this study we identify the most likely changes in crop species and varieties in Finland and the pest and pathogen species that are most likely to create production problems as a result of climate change during this century.;
Full Text Available Climate change and associated uncertainties have serious direct and indirect consequences for crop production and food security in agriculture-based developing regions. Long-term climate data analysis can identify climate risks and anticipate new ones for planning appropriate adaptation and mitigation options. The aim of this study was to identify near-term (2030 and mid-term (2050 climate risks and/or opportunities in the state of Bihar, one of India’s most populous and poorest states, using weather data for 30 years (1980–2009 as a baseline. Rainfall, maximum and minimum temperatures, and evapotranspiration will all increase in the near- and mid-term periods relative to the baseline period, with the magnitude of the change varying with time, season and location within the state. Bihar’s major climate risks for crop production will be heat stress due to increasing minimum temperatures in the rabi (winter season and high minimum and maximum temperatures in the spring season; and intense rainfall and longer dry spells in the kharif (monsoon season. The increase in annual and seasonal rainfall amounts, and extended crop growing period in the kharif season generally provide opportunities; but increasing temperature across the state will have considerable negative consequences on (staple crops by affecting crop phenology, physiology and plant-water relations. The study helps develop site-specific adaptation and mitigation options that minimize the negative effects of climate change while maximizing the opportunities.
